3) Heat exchanges occur inside a calorimeter with 0.01248 mol iron (III) oxide, Fe, O3, and 985 g water. The final temperature change of the mixture is 2.58°C. Using the specific heat
capacity of water as 4.184 J/gºC, determine the amount of heat in kJ given off per mol of
Fe2O3.

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

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