a) During a hypothetical process, the entropy of a system increases by 105 J/K while the entropy of the surroundings decreases by 95 J/K. Is the process spontaneous? Is the process reversible?

b) What happens if the opposite process occurs, i.e. entropy of the system dcreases by 105 J/K and the entropy of the surroundings increases by 95 J/K?
