Step 2

Rate law expression for any chemical reaction is any equation that relates the rate of that reaction with the concentrations of the reactants. help_outlineImage TranscriptioncloseFor example, for a the reaction- A+B -> C+D The rate law expression is - Rate k [A BJ Where k is the rate constant And x and y are the order ofreaction of A and B respectively fullscreen
