Discussion chemical Equilibria and kinetics Essay
A. Effect of Nature of Reactants to the reaction rate.
B. Effect of Temperature to the reaction
C. Effect of Concentration to the Reaction Rate
D. Effect of Catalyst to the Reaction Rate
E. Chromate-Dichromate Equilibrium
F. Thiocyanatoiron (III) Complex Ion Equilibrium
G. Weak Acid Equilibrium (Ionization of Acetic Acid)
H. Weak Base Equilibrium Ionization of Ammonia
I. Saturated Salt (Sodium Chloride) Equilibrium
On part (A) we are to observe which reaction rate is faster, and doing the experiment. We have concluded that:
“Aluminum had faster rate of reaction rate than iron because it is more active than iron based on the activity series.”

If the starting conditions are 100% B, as in (ii), the kinetics at very early times (leftmost region of the graph) are dominated by the reverse reaction, B → A. Once some A forms, the rate of the forward reaction begins to pick up. The net rate still favors production of A for a short time (middle graph), but its concentration levels off by ~60 s, having attained equilibrium level. Notably, these equilibrium conditions are the same as those in (i) - this assumes both experiments are carried out at the same temperature.
