A catalyst lowers the activation energy ...

A catalyst lowers the activation energy of a reaction from 20 kJ mol^(-1) to 10 kJ mol^(-1). The temperature at which uncatalysed reaction will have same rate as that of catalysed at 27°C is

A

`50^(@)C`

B

`225^(@)C`

C

`323^(@)C`

D

`596^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
C
`(E_(a_(1)))/(T_(1))=(E_(a_(2)))/(T_(2))`
`200/(T_(1))=100/298`
`T_(1)=596K=323^(@)C`
