rate law for the reversible storage of energy by the NQ couple. P3-168 What five things are wrong with this solution? The reaction 2A +BC follows an elementary law. At 50C the specific reaction rate constant is 10(m?/mol)-/s with an activation energy of 400J/mol. What is the rate of reac- tion at 100C when the concentrations of A and B are 2 and 4 moles/m respectively? Solution In order to completely consume a 4 molar solution of B would require an 8 molar concentration of A. Because the initial concentration of A is only 2 molar, A is the limiting reactant. Thus we choose A as our basis of calculation and divide by its stoichiometic coefficient of A, to get A+ because the reaction follows an elementary rate law -r = kc CB2 Converting the rate constant at 50C to k at 100C ( K(100C) = (50C)exp(KG, 7) 100] 4005 1 10exp 1.98 50 100 = 75.4(m /mol)/s Substituting for k, CA and CB -TA = (75.4)(2)(4)/2 = 301 mol 3 m.h
