Part A Calculate the enthalpy change, delta H,for the expansion of methane CH4(g)->C(g)+4H(g) Part B Calculate the enthalpy change, delta H for the reverse of the formation of methane

Part A Calculate the enthalpy change, delta H,for the expansion of methane

CH4(g)->C(g)+4H(g)

Part B

Calculate the enthalpy change, delta H for the reverse of the formation of methane.

CH4(g)->C(s) + 2H2(g)

Part C

Suppose that 0.570 mol of methane CH4(g) is reacted with 0.720 mol of fluorine ,F2(g),forming CF4(g) and HF (g) as sole products. Assuming that the reaction occurs at constant pressure,how much heat is released?
