Question

Assertion :For the reaction $N_2\left(g\right)+3H_2\left(g\right)⟶2N{H}_3\left(g\right)$ Unit of $K_c=L^{2}mo{l}^{-2}$ Reason: Equilibrium constant, $K_c=\frac{[N{H}_3{]}^2}{\left[N_2\right][H_2{]}^3}$

Read the above assertion and reason and choose the correct option regarding it.

• 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. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Units for concentration is $mol/L$.

Units for $K_c$ will be ${\left(mol/L\right)}^2$/$\left(\right(mol/L{)}^{-1}$$\times$$\left(mol/L{)}^{-3}\right)$=$L^{2}mo{l}^{-2}$
