Chapter 8, Problem 8.14E

Consider the following hypothetical reaction:

$A+B\to C$

Calculate the average rate of the reaction on the basis of the following information:

a. Pure $A$ and $B$ are mixed, and after $\text{12}\text{.0}\text{minutes}$ the measured concentration of $C$ is $0.396\text{mol}/\text{L}$.

b. Pure $A,B$, and $C$ are mixed together at equal concentrations of $0.300\text{M}$. After $\text{8}\text{.00}\text{minutes}$, the concentration of $C$ is found to be $0.455\text{M}$.
