If 19.3 moles of heptane (C7H16) are reacted with an excess of oxygen gas, how many moles of carbon dioxide (CO2) should be produced? (Round to the tenths place)

1 C7H16 + 11 O2 -> 7 CO2 + 8 H2O

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
