Part (c) - Reaction Kinetics

Here are the solutions to the chemistry questions:

Part (c) - Reaction Kinetics

i) The rate of a reaction is the change in the concentration of a reactant or product per unit time.

ii) The overall order of a reaction is the sum of the exponents of the concentration terms in the experimentally determined rate equation.

iii) To determine the rate equation, we first find the order of reaction with respect to each reactant using the given experimental data.
Let the rate equation be $\text{Rate} = k[\text{HgCl}_2]^x[\text{C}_2\text{O}_4^{2-}]^y$.

Comparing Experiment 1 and Experiment 2:
$[\text{HgCl}_2]$ is constant
