Thermochemistry reveiw assignment answers StuDocu . The equation 2H2(g) + ½ O2(g) → 2 H 2 O(g) + 483 kJ is an exothermic reaction. For the reaction: if the rate of production of H 2 is 0 mols/sec, then the rate with respect to HCl r = -0 mols HCl/sec. The value of the rate constant, k, is valid only for a specific reaction at a specific temperature.
