Consider a hypothetical equilibrium that exists between compounds A and B at room temp (298 K). The ?G‡ for the forward reaction (conversion of A to B) is 22 KJ/mol. Likewise ?G‡ for the reverse process is 34 KJ/mol. A. Calculate ?G0 for the forward reaction and construct a potential energy diagram for the conversion of A to B. Be sure to place the transition state in accordance with the Hammond Postulate. B. a flask containing a mixture of A and B at equilibrium was discovered, and the concentration of A at room temperature was determined experimentally to be 3.1 x 10^-2 mol/L. What is the concentration of B?
