Solution: Ethane is C2H6. Consider the reaction below:  C2H6(g) ⇋ 2 Cgraphite(s) + 3 H2(g)  ∆G◦rxn = 7.86 kJ · mol−1 The decomposition of ethane is (spontaneous/non-spontaneous) and therefore ethane is (stabl

Problem

Ethane is C2H6. Consider the reaction below: 

C2H6(g) ⇋ 2 Cgraphite(s) + 3 H2(g) 

∆Grxn = 7.86 kJ · mol−1 The decomposition of ethane is (spontaneous/non-spontaneous) and therefore ethane is (stable/unstable).

1. spontaneous, unstable

2. spontaneous, stable

3. non-spontaneous, unstable

4. non-spontaneous, stable
