The hydrogenation of ethene gas under standard conditions (T=298K) shows a decrease in disorder (delta S = -0.1207 kJ/mol x K)) during an exothermic reaction (delta H degrees = -136.9 kJ/mol). Determine whether the reaction is spontaneous or nonspontaneous by calculating delta G degrees.

C2H4 (g) + H2 (g) -> C2H6 (g)

An electric kettle uses electrical energy to boil water. energy from the electricity is transferred to the water, heating it up. an electric ice maker also uses electrical energy, but it freezes water to form ice. since energy can’t be created or destroyed, and water loses potential energy when it freezes to form ice, what happens to the energy put into the ice maker and the energy released by the water?
