## Effect on rxn rate

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

### Effect on rxn rate

How do you know how the rate of a reaction will be affected if you double/halve/ etc. the amount of a product or reactant?

This would all depend on which order the reactants are at. For example, for a first order reaction, the rate of the reaction will be proportional 1:1 with the reactant, while in a second order reaction, the rate of the reaction would be exponential to the factor of two as compared with the reactant.

This depends on the order of the reactant. If the order is 1, and the concentration is doubled, the overall rate doubles. If the order is 2, however, the overall rate would quadruple.
