Question

(d) between-40 and +100 k.J (e) greater than +100 kJ S Which describes the change in AG and the change in spontaneity of the reaction as temperature increases? (a) decreases to values less than zero and the reaction achieves equilibrium (b) G decreases to values less than zero and the reaction becomes spontaneous. (c) G decreases to values less than zero and the reaction becomes nonspontaneous. (d) G increases to values greater than zero and the reaction becomes spontaneous. (e) G increases to values greater than zero and the reaction becomes nonspontaneous

Explanation / Answer

Option a is correct.if we want to know whether or not a reaction is favored by an increase or decrease in temperature we really need to be looking at the equilibrium constant. If the equilibrium constant increases with temperature the reaction becomes more favored, but if the equilibrium constant decreases with temperature the reaction becomes less favored. DelG should be less than zero that is negative for the reaction to be spontaneous
