During all chemical reactions, charge, mass and energy are (A) Condensed
(B) Conserved
(C) Decayed
(D) Decomposed

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

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.

Under which circumstances are kp and kc equal for the reaction aa(g)+bb(g)⇌cc(g)+dd(g)?
