For the reaction 2A  + 3B  –>  4C  + 5D  + 170kJ If A has a molar mass of 38 g/mole and B has a molar mass of 46 g/mol,   a) how much energy could be produced if you had 265g of A and 400g of B?   b) What would be the rate if the rate constant was 2.4 M-3s-1 when A is second order, and B is second order at the moment when [A] = 0.65M, [B] = 0.78M?
