I need help..I just need the balanced equation and reaction type for reactions 1-6 and the question answered for reaction 1, the second question for reaction 2, the second question answered for reaction 3, the second question for reaction 5, and the second question for reaction 6.

Solid tin exists in two forms: white and gray. for the transformation sn(s, white) → sn(s, gray) the enthalpy change is -2.1 kj/mol and the entropy change is -7.4 j/(mol*k). a. calculate the gibbs free energy change for the conversion of 1.00 mol white tin to gray tin at -30℃. b. will white tin convert spontaneously to gray tin at -30℃? c. at what temperature are white and gray tin thermodynamically equivalent at a pressure of 1 atm?
