If the activation energy is decreased by...

If the activation energy is decreased by `(5x)` % by using a catalyst (300K) to achieve the same effect as of increasing the temperature from 300K-400K in a reaction, then find x.

Text Solution

Verified by Experts

The correct Answer is:
5
`r_(1)=r_(2),A.e^(-E_(a1)//RT_(1))=A.e^(-epsilon_(a_(2))//RT),((E_(a_(1)))/(T_(1)))_("cat")=((E_(a_(2)))/(T_(2)))_("No cat"),(E_(a)(100-y))/(300xx100)=(E_(a))/400,y=25%=5x%impliesx=5`

Convert the temperature of 300K to Celsius scale.

Arrhenius studied the effect of temperature on the rate of a reaction and postulated that rate constant varies with temperature exponentially as k=Ae^(-E_(a)//RT) . For most of the reactions it was found that the temperature coefficient of the reaction lies between 2 to 3. The method is generally used for finding the activation energy of a reaction. Keeping temperature constant, the effect of catalyst on the activation energy has also been studied by studying how much the rate of reaction changes in the presence of catalyst. In most of the cases, it is observed that catalyst lowers the activationenergy barrier and increases the rate of reaction. If the rate oc reaction grwos 15.6 times on increasing the temperature by 30 K the temperature coefficient of the reaction will be nearly
