Rate law with 2 reactants

Postby Jaira_Murphy_2D » Tue Mar 12, 2019 2:07 pm

What is the rate law if the reaction is in 1st order, but there are 2 reactants?

Hi! I think if there are two reactants and the reaction is first order, that means the reaction is not the mechanism and you have to do an experiment to see which reactant affect the overall rate.

one of the reactants is 0th order, so the rate only depends on the concentration of the other one. When you write the overall rate law, you only include the reactants with order>0.

one reactant is zero order and one is in first order
