A hydrogenation reaction is carried out ...

A hydrogenation reaction is carried out at 500 K. If the same reaction is carried out in the presence of a catalyst at the same rate with same frequency factor, the temperature required is 400 K. What is the activation energy of the eaction. If the catalyst lowers the activation energy barrier by 16 KJ/mol?

A

100kJ/mol

B

80kJ/mol

C

60kJ/mol

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
`r_(1)=r_(2),K_(1).(C_(0))^(n)=K_(2).(C_(0))^(n),A.e^(-Ea//RT_(1))=A.e^(-epsilona_(2)//RT_(2))`
`(epsilon_(a_(1)))/(T_(1))=(epsilon_(a_(2)))/(T_(2)),(epsilon_(a_(1)))/600=((epsilon_(a_(1))-16))/400,4epsilon_(a_(1))=5(epsilon_(a_(1))-16),4epsilon_(a_(1))=5epsilon_(a_(1))-80,epsilon_(a_(1))=80`

(A)Catalyst increases the rate of reaction. (R ) Catalyst functions by lowering the energy of activation.

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
