In the presence of catalyst, the activation energy of the reaction is lowered by 2 kcal at `27^(@)C`. The rate of reaction will increased by

A

2 times

B

4 times

C

28 times

D

20 times

Text Solution

Verified by Experts

The correct Answer is:
C
We have theh relationship between catalysed and uncatalysed reaction on
`(K_(UC))/(K_(C))=e(DeltaEa)/(RT)=e(2xx1000)/(2xx300)=28`

In the presence of a catalyst, the activation energy is lowered by 3 Kcal at 27^(@) c .Hence the rate of reaction will increase by :

At 227^(@)C , the presence of catalyst causes the activation energy of a reaction to decrease by 4.606 K cal. The rate of the reaction will be increased by : -

For a given reaction, presence of catalyst reduces the energy of activation by 2 kcal at 27^(@)C . Thus rate of reaction will be increased by:

A poistive catalyst increases the activation energy of the reaction.

In presence of a catalyst, the activation energy is lowered by "2" kcal at \(127^{o}\)C .Hence, the rate as compared to the old rate is \(e^{x}\) times. then the value of "x" is
