For a general equation of the nature xP + yQ → mR + nS, the expression for the equilibrium constant is

  • A k [P]x [Q]y
  • B \(\frac{[P]^x [Q]^y}{[R]^m [S]^n}\)
  • C \(\frac{[R]^m [S]^n}{[P]^x [Q]^y}\)
  • D \(\frac{m[R] n[S]}{x[P] y[Q] }\)

The correct answer is C. \(\frac{[R]^m [S]^n}{[P]^x [Q]^y}\)

Expression for equilibrium constant

k = \(\frac{\text{concentration of product}}{\text{concentration of reactant}}\)
