Question

Assertion (A): Rate of reaction will be doubled, when temperature increased from 298 k to 308 k.
Reason (R): The activation energy of reaction decreases with increase in temperature.
A true but (R) is false
D)
2) BoA) (R) are true (R) is the correct explanation to (A)
BA(R) are true but (R) is sot the correct explanation to (A)
BAR) se false​

Answer 1

Explanation:

A rate of reaction of most of the reactions doubles, when temperature increased from 298 K to 308 K.

The activation energy of the reaction is not affected with an increase in temperature.

But as the temperature increases, the number of molecules having energy equal to or greater than activation energy increases. This increases the number of effective collisions and the rate of the reaction.

The assertion is correct but Reason is incorrect.

Answer 2

Answer:

Assertion is true  but reason is false.
