Equilibrium constant for Ideal gases in terms of partial pressure is denoted by?

Correct answer: C. Kp

  • A. Kc
  • B. K
  • C. Kp
  • D. None of these

Explanation

Option A is wrong because Kc is not the equilibrium constant for ideal gases in terms of partial pressure. Option B is wrong because K is not the equilibrium constant for ideal gases in terms of partial pressure. We also have to put 'p' (initial of pressure) along with K to make it the correct equilibrium constant in terms of partial pressure. Option: C Kp is the equilibrium constant calculated from the partial pressures of a reaction equation. It is used to express the relationship between product pressures and reactant pressure.

About Reversible Reactions

A reversible reaction proceeds in both forward and backward directions, so reactants and products continue changing until dynamic equilibrium is established. The topic covers the meaning of equilibrium, the equality of forward and reverse rates, and how concentration, pressure and temperature disturb equilibrium, which is separate from the rate at which equilibrium is reached.
