Question

Assertion: Temperature coefficient of a one-step reaction may be negative.
Reason: The rate of reaction having a negative order with respect to a reactant decreases with the increase in the concentration of the reactant

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
• C. Assertion is true but Reason is false
• D. Assertion is false but Reason is true
• E. Both Assertion and Reason are false

Answer 1

Answer: (D)

Assertion is false but Reason is true

Temperature coefficient refers to the ratio of rate constants of a chemical reaction, affected by $10°$rise in temperature.That is for every $10°$rise in temperature, rate of reaction is doubled.The rate of reaction having a negative order with respect to a reactant decreases with the increase in the concentration of the reactant.
