Multiple choice

For the equilibrium established between butane and isobutane, if the volume of the container is halved, the equilibrium will

  1. shift in forward direction

  2. not change

  3. shift in backward direction

  4. shift randomly
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This option is correct and can be explained as follows: The equilibrium constant for the reaction in the given question is given ask  =  [Butane]/[Isobutane].   However on decreasing the volume of the container the individual concentration of butane and isobutane increases but the overall change in equilibrium constant will be zero as the increase in concentrations of reactant and products will be cancelled.
