Question
What is the correct equilibrium constant expression or equation for the reactionH2(g) + Cl2(g) ⇋ 2HCl(g) Question 2Select one:a.b.c. d.
Solution
The equilibrium constant expression for the reaction H2(g) + Cl2(g) ⇋ 2HCl(g) is given by the law of mass action as:
Kc = [HCl]^2 / ([H2] [Cl2])
Where:
- Kc is the equilibrium constant
- [HCl], [H2], and [Cl2] are the molar concentrations of HCl, H2, and Cl2 at equilibrium, respectively.
The exponents in the expression are equal to the stoichiometric coefficients in the balanced chemical equation.
