Two substances in a mixture differ in density and particle size. these properties can be used to
1) seperate the substances
2) chemically combine the substances
3) determine the freezing point of the mixture
4) predict the electrical conductivity

Consider the following multistep reaction: a b→ab(slow) a ab→a2b(fast)−−−−−−−−−−−−−−−−− 2a b→a2b(overall) based on this mechanism, determine the rate law for the overall reaction. express your answer in standard masteringchemistry format. for example, if the rate law is k[a]3[b]2 type k*[a]^3*[b]^2
