Question

Assertion :$K_p$ can be equal to or less than or even greater than the value of $K_c$ Reason: $K_c=K_p(RT{)}^{-\Delta n}$ relation between $K_p$ and $K_c$ depends on the change in the number of moles of gaseous reactants and products.

• 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

$K_c=K_p(RT{)}^{-\Delta n}$ is the relation between $K_p$ and $K_c$ and depends on the change in the number of moles of gaseous reactants and products. Hence, $K_p$ can be greater or less or equal to $K_c$.

Note:

If,

i) $\Delta n=0;K_p=K_c$.

ii) $\Delta n>0;K_p>K_c$.

ii) $\Delta n<0;K_p<K_c$.
