JEE Main 2020 — Chemical Equilibrium Question with Solution

JEE Main 2020 (05 Sep Shift 2)

Question

For a reaction X+Y=2Z,1.0mol of X,1.5mol of Y and 0.5mol of Z were taken in a 1L vessel and allowed to react. At equilibrium, the concentration of Z was 1.0molL-1. the equilibrium constant of the reaction is …………x15. The value of x is …….

Correct answer
16

Step-by-step explanation

            x   +   y=   2 z

t=0 1mol  1.5mol  0.5mol

Since moles of Z are increased at equilibrium therefore reaction goes in forward direction to attain the
equilibrium.
