Determine if the following statements are true or false. Half life is the time required for the concentration of the reactants to decrease by one half The rate law: rate = k[A][B] will simplify to rate = k'[B] if a large excess of reagent A is used The first order half life equation can be applied to any order reaction Pseudo-order reaction kinetics is a way to simplify a more complicated rate law by holding one (or more) of the reagents essentially constant
