The reaction between Propanone and iodine under acidic condition

Aims
To find the order of reaction with respect to propanone, iodine and sulfuric acid, thus proposing a rate equation.
Find rate constant at various temperature and with the use of the Arrhenius equation, find the activation enthalpy of the reaction.

General Method {For step by step guide of the experiment see preparation page}
By using known concentration of aqueous iodine solution (0.000 moldm-3, 0.005 mol dm-3, 0.015 moldm-3, 0.020 moldm-3, 0.025 moldm-3, 0.030 moldm-3, 0.035 moldm-3, 0.040 moldm-3, 0.045 moldm-3, 0.050 moldm-3, 0.055 moldm-3) and a colorimeter, find the absorbance for each of the concentrations. This can then be used to to plot a calibration curve (concentration
To enable them to react we can either change the shape of the curve or move the activation energy (explain later on keep reading).

One of which is to increase the temperature of the reaction. As temperature increases the rate of reaction increases. This is because the particles becomes more energetic causing them to have more kinetic energy as a result they move faster and more collisions occur with the required Ea (collision frequency increases). Using this knowledge, to speed up a reaction, there needs to be an increase in the number of energetic particles (those with energies equal to or greater than the activation energy) and by increasing the temperature has that effect (changes the shape of the graph) as shown below.

Curve T: Original temperature
Curve T+t: At higher temperature

Comparing to our original curve (Figure 1.1, Curve T). Curve T+t shows the effect of temperature increase. More particles have the activation energy meaning more successful collisions occur which then leads to reaction, hence seeing the increase of the area under the Curve

Effect of Surface area: If there is a greater surface area of a reactant there is a bigger chance of a collision occurring between the particles. If one of the reactants is a solid then breaking it up into smaller pieces will increase the surface area. This means the particles around it in the solution will have more to work to do so there will be more useful collisions. Effect of Concentration: Increasing the concentration means you are adding more particles to a solution which also increases the reaction time. If the concentration of any reactant in a solution is increased, the rate of reaction is increased.…

Both of these factors result in the structure of FeO4 to change in size as temperature increases. By the same token, the O-P-O angles change as temperature increases, while the P-O bond distances change as temperature increases. This results in a change in size in the structure of PO4 as temperature increases. The equation δ^2 = 2/3 δ0^2 [1 + (1 – ¾ (T – Tc/T0 – Tc))^1/2] can be used here to describe quantitatively how the temperature affects the cell parameter and size, as we have earlier established how temperature affects the tilt angle which affects the cell parameter and…

Heating up the solvent gives the molecules more kinetic energy. The faster motion means that the solvent molecules collide with the solute with a higher frequency and the collisions occur with more force. Both components help to increase the rate at which the solute dissolves. A change of temperature does not only affect the rate of dissolving, but it also affects the amount of solute that…

At high pH, where FeS formation is favorable, the increase in PH2S will increase sulfide ion and sulfide ion concentration, followed by higher super saturation of FeS. High iron sulfide super saturation enhances precipitation and scale formation. Nesic et al. showed that when PH2S is increased, pH at the surface initially increases due to corrosion and release of Fe2+, and then decreases since precipitation of FeS occurs rapidly. They also concluded that at constant pH, as PH2S increases, FeS precipitation can increase faster than the corrosion…

These will lead to an increase in the conversions of gas oil and subsequent increase in the yield of the products. There will also be an increase in the sensible heat accompanying the catalyst, hence there is an initial increase in the riser outlet temperature but as reaction proceeds, the increased cracking reaction causes an increase in the heat absorbed and results in a decrease in the outlet temperature until steady state is attained (Akpa et al.…
