Question

Assertion :For a 2nd order reaction, $A+B\to Product$, the rate can be given as: $K[A{]}^2$ or $K\left[A\right]\left[B\right]$ or $K[B{]}^2$. Reason: Either [A] or [B] may or may not influence the rate of reaction.

• 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 A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

For the second-order reaction $A+B⟶Products$

The rate of reaction can be $k[A{]}^2$ or $k\left[A\right]\left[B\right]$ or $k[B{]}^2$. All the rates are of second order.

The assertion is correct.

The concentrations of A or B may or may not influence the rate of reaction.

Reason is the correct explanation for Assertion.
