Which statement concerning a possible mechanism for a reaction is false?
a) a possible mechanism must be consistent with the experimental data.
b) the speed of the slow step limits the rate at which the overall reaction occurs.
c) for all the reactions the experimentally determined reaction orders of the reactants indicate the number of molecules of those reactants involved in the slow step of the mechanism.
d) each elementary step is represented by a balanced equation.
e) the elementary steps must add to give the equation for the overall reaction

The combustion of methane, ch4, releases 890.4kj/mol. that is, when one mole of methane is burned,890.4 kj are given off to the surroundings. this meansthat the products have 890.4 kj less than the reactants. thus, ah for the reaction = - 890.4 kj. a negative symbolforah indicates an exothermic reaction. ch (g) + 20 (g)> co2 (g) + 2 h0 (1); ah = - 890.4 kga) how much energy is given off when 2.00 mol of ch, are burned? b) how much energy is released when 22.4g of ch. areburned?
