Which of the following reactions is a heterogeneous equilibria expression?
A. 2NO(g) + O2(g) <---> 2NO2(g) B.2NH3(g)<---> N2(g) + 3H2(g) C.2H2(g) + O2(g)<---> 2H2O(g) D.2S(s) + 3O2(g)<---> 2SO3(g)
Solution 1
The answer is D. 2S(s) + 3O2(g)<---> 2SO3(g). This is a heterogeneous equilibrium because it involves substances in different phases. In this case, sulfur (S) is in the solid phase (s) and oxygen (O2) and sulfur trioxide (SO3) are in the gaseous phase (g). The other reactions are homogeneous equilibria because they involve substances in the same phase.
Solution 2
The answer is D. 2S(s) + 3O2(g)<---> 2SO3(g). This is a heterogeneous equilibrium because it involves substances in different phases. In this case, sulfur (S) is in the solid phase (s) and oxygen (O2) and sulfur trioxide (SO3) are in the gaseous phase (g). The other reactions are homogeneous equilibria because they involve substances in the same phase.
Solution 3
The answer is D. 2S(s) + 3O2(g) <---> 2SO3(g).
This is a heterogeneous equilibrium because it involves substances in different phases. In this case, sulfur (S) is in the solid phase (s) and oxygen (O2) and sulfur trioxide (SO3) are in the gaseous phase (g).
In contrast, options A, B, and C are homogeneous equilibria because all reactants and products are in the same phase (gaseous).
