9) What is the symbolic expression for the equilibrium constant for the reaction:
2 C2H6(g) + 7 O2(g) ⇌ 4 CO2(g) + 6 H2O(g)?

The equilibrium constant expression (Kc) for this reaction is as follows:

Kc = [CO2]^4[H2O]^6 / [C2H6]^2[O2]^7

Therefore, the symbolic expression for the equilibrium constant for the given reaction is:
Kc = [CO2]^4[H2O]^6 / [C2H6]^2[O2]^7
