For each calculate ∆Hrxn, ∆Srxn, and ∆Grxn, at 25 degrees celsius and state whether or not the reaction is spontaneous. If it is not, would a change in temperature make it spontaneous? If so, what would the temperature change need to be?

a. 2CH4 (g) --> C2H6 (g) + H2 (g)

b. 2KClO3(s) --> 2KCl (s) + 3 O2 (g)
