## 6th edition 15.39

$\frac{d[R]}{dt}=-k[R]^{2}; \frac{1}{[R]}=kt + \frac{1}{[R]_{0}}; t_{\frac{1}{2}}=\frac{1}{k[R]_{0}}$

### 6th edition 15.39

For part A of question 15.39 from the 6th edition, how does the coefficient in front of the reactant affect the equation? If it was just A -> B + C would it still be the same answer?

For part a, the coefficient does not affect the rate law equation.

the rate law isn't directly related to the coefficients of the reactants
