## How the concentration of a reactant affects the rate of the reaction

$aR \to bP, Rate = -\frac{1}{a} \frac{d[R]}{dt} = \frac{1}{b}\frac{d[P]}{dt}$

### How the concentration of a reactant affects the rate of the reaction

What are some of the ways that the concentration of a reactant affects the rate of the reaction ?

More of the reactant means that the probability of collisions can occur more frequently which means the reaction is more likely to proceed faster.

Based on the order of a reactant, the rate of the reaction can be affected by its concentration or its concentration squared (first and second order respectively). In case of zero order, its concentration would not affect the rate at all.

depending on order, raise the effect on the concentration to that power to see the effect on the rate. for example if we double the concentration of a 1st order than you do 2^1 (1 because 1st order) which equals 2 meaning the rate will also be doubled. for 2nd order it would be 2^2 meaning the rate would be multiplied by 4
