On doubling P and V with constant temperature the equilibrium constant will
Options
(a) remain constant
(b) become double
(c) become one-fourth
(d) none of these
Correct Answer:
remain constant
Explanation:
On doubling P and volume with constant T, the equilibrium constant (K) will remain constant. Pressure will never affect the value of K. It may result in the shifting of equilibrium but not the equilibrium constant value. Temperature always changes K because on adding heat to a system in state of equilibrium will always alter the forward reaction rate differently than the reverse reaction rate. Also by doubling the volume, the concentrations of both reactants and product evenly become half. Therefore, overall there is no change in equilibrium constant value (K).
