59. Solving a chemistry problem

4. Calculate the change in the standard Gibbs free energy and draw a conclusion about the direction of the process at the specified temperature. Calculate the temperature of equal probability of direct and reverse processes. Make a conclusion about the direction of the process above and below this temperature. Use reference data to solve. Ignore the temperature dependence of ΔH and ΔS.
