CHXI07:EQUILIBRIUM

314783 Assertion :
Benzoic acid \(\left( {{{\text{K}}_{\text{a}}}{\text{ = 6}}{\text{.5}} \times {\text{1}}{{\text{0}}^{{\text{ - 5}}}}} \right)\) is stronger acid than acetic acid
\(\left(\mathrm{K}_{\mathrm{a}}=1.74 \times 10^{-5}\right)\).
Reason :
Larger the value of \(\mathrm{K}_{\mathrm{a}}\), greater is the acidity .

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
