Question

Assertion :The value of equilibrium constant depends on the stoichiometry of the equation. BECAUSE Reason: The value of equilibrium constant does not change when the equation is multiplied or divided by a number.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Assertion is incorrect but Reason is correct

Answer 1

The correct option is C Assertion is correct but Reason is incorrect

The value of equilibrium constant depends on the stoichiometry of the equation. BECAUSE
The value of equilibrium constant changes when the equation is multiplied or divided by a number.
Assertion is correct but Reason is incorrect.
Consider the reaction $A+B\to C+D$ $K=\frac{\left[C\right]\left[D\right]}{\left[A\right]\left[B\right]}$
Multiply above reaction with 2.
$2A+2B\to 2C+2D$ $K^{\prime }=\frac{\left[C{]}^2\right[D{]}^2}{\left[A{]}^2\right[B{]}^2}=(\frac{\left[C\right]\left[D\right]}{\left[A\right]\left[B\right]}{)}^2=K^2$
