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)

The Rutherford model shows that an atom is mostly empty space, with electrons orbiting a fixed, positively charged nucleus in set, predictable paths.
