Question

For the system $3A+2B\to 2C$, the expression for equilibrium constant $K$ is:

• A. $\frac{\left[3A\right]\times \left[2B\right]}{\left[C\right]}$
• B. $\frac{[A{]}^3\times [B]}{\left[C\right]}$
• C. $\frac{[C{]}^2}{[A{]}^3\times [B{]}^2}$
• D. $\frac{\left[C\right]}{\left[3A\right]\times \left[2B\right]}$

Answer 1

The correct option is C $\frac{[C{]}^2}{[A{]}^3\times [B{]}^2}$

For the reaction:

$3A+2B\to 2$

Equilibrium constant, $K=\frac{[C{]}^2}{[A{]}^3\times [B{]}^2}$
