Arrhenius equation

0.20 g of adsorbent was added to 20 mL of 50 mg/L dye solution and Vortex at 150 rpm for various time intervals at 5, 10, 15, 30, 60, minutes. The above steps were repeated using dye concentrations of 100, 150 and 200 mg/L dye solutions. Adsorbent dosage is an important parameter because it determines the capacity of adsorbent for a given initial concentration of dye molecules. Then their % absorbance’s were calculated by spectrophotometer (λmax=410) and thus amount adsorbed were calculated.…

Coulomb interaction operator, is a spherically symmetric component of the polarization energy operator, and ( herrU,ˆ ()rVˆ is the dielectric solvation energy operator. To obtain the explicit form of these operators we solve analytically the Poisson equation for a potential due to a point charge in the core/shell structure with the standard boundary conditions that account for discontinuity of the dielectric constant at hetero-interfaces.3 As a result, we obtain the following solutions: 3…

Asset and Liability Management A credit side of a US bank’s balance sheet typically included floating-rate liabilities and long-term fixed-rate liabilities, whereas debit side consisted of floating-rate assets and long-term fixed-rate assets. Generally speaking, asset and liability management required the banks to match the economic characteristics of its cash in and out and the strategic decisions relative to interest rate exposure required banks to match their assets to liabilities effectively…

CFO Tool 3 & 4 Whoever you are, and whatever income or debt you have, I think it is important to try to think of yourself like a business entity. Like a business you will have income and expenses. A balance sheet and an income statement tell a business what they are worth, defines income and spending, and also helps the firm set and measure goals. Both of these tools are useful for long term planning. A business is often measured by profits, and your budget is the same way. Since the…

functions, otherwise the equation will not be able to solve. An important rule to understand when deriving the quadratic formula by completing the square, is that the leading term must equal to “1”. On the other hand, if the leading term does not equal to “1”, one will have to factor the equation by dividing each term by the leading term. The quadratic equation must start as the following: 〖ax〗^2+bx+c=0. Next, the constant number is to be moved to the other side of the equation. Another…

INVESTIGATE AN ASPECT OF REDOX SYSTEM/REACTION Research Question: Does a higher voltage lead to more mass on graphite? INTRODUCTION Hypothesis: Higher voltage leads to more mass amassed on graphite electrode. Electrolysis- the process in which electric current passes through a solution to effect a chemical change. In this case there is copper, copper sulphate and graphite. In a electrolysis there is an electrolyte which is the copper sulphate, the anode which is the graphite. This is the…

at . Next, Hopf bifurcation at : The Jacobian matrix corresponding to is given by (36) where and its nonzero elements are defined as in (14) and (15) with & replaced by & respectively. The characteristic equation corresponding to obeys (37) where the coefficients are defined as in (16). By the Routh–Hurwitz criteria, all the roots of (37) will have negative real parts if , and It is required for a Hopf bifurcation that…

In a chemical equation, there are the reactants, which is the part that is changed, and the products, which is what is left over. The reactant side and the product side must have the same quantity of each element. If they do not, the equation must be balanced by using coefficients. Mole ratios can be found by using these coefficients. Mole ratios are conversion factors and can be used to found the amounts of the reactants and the products in a chemical reaction. These can also be used to find…

concentration of the the crystal violet and hydroxide ions. Using the integrated kinetics method, the rate law can be calculated for single reactant when converted to products, as well as the value of the rate constant, K, by the integrated rate law equations: Zero Order: First Order:…

in which the vessel will travel. They take no time to consider that an unforeseen variable could spiral into the equation. The algorithm developed to produce their answer leaves no room for error, after-all it is a formula birthed by the forces that keep planets spinning and maintain gravitational pressure, human hands cannot alter the design of such a thing. The product of the equation is exact. There are never miscalculations, only misconceptions about what the answer should have been made…
