Question

A chemical reaction $X\rightleftharpoons Y$ is said to be in equilibrium when -

• A. 50% of the conversion has taken place
• B. only 10% conversion of X to Y has taken place
• C. the rate of transformation of X to Y is equal to the rate of transformation of Y to X in the system
• D. there is change in the concentration of either x or y

Answer 1

The correct option is C

the rate of transformation of X to Y is equal to the rate of transformation of Y to X in the system

At equilibrium state, rate of forward reaction becomes equals to rate of reverse reaction
