Assume in each case that the temperature is 300 K and the value of R is .008 kJ/mol K. Assume the reaction in each case is A <=> B
1. At equilibrium, the ratio of products to reactants is 2/1. What is the value of Delta Gzeroprime?
2. If the ratio of products to reactants in problem #1 is changed to 1/2, will the forward or the reverse reaction be favored? Why?
Forward. Delta G will become -3.32 kJ/mol
3. A reaction has a Delta Gzeroprime of -10 kJ/mole and the ratio of products to reactants is 2/1. Which direction will the reaction go?
Forward. Delta G will be -8.34 kJ/mol
