Question

What is the standard molar entropy change (∆S°) for the reaction: 2HBr(g) + Cl2(g) -> 2HCl(g) + Br2(g) if the standard molar enthalpy change (∆H°) is -107.6 kJ/mol?

Answer 1

To calculate the standard molar entropy change  S  for the reaction, we need to use the Gibbs free energy equation:G = H - TSHowever, we are not given the standard molar Gibbs free energy change  G  or the temperature  T  in the problem. We need more information to solve this problem.
