Question

Which of the following is wrong ?
A) A catalyst lowers the activation energy barriers for the forward and reverse reaction
B) A catalyst increase the rate constant for backward and forward reaction
C) For endothermic reaction increasing the temperature increase the rate constant of forward reaction more than backward reaction D) For endothermic reaction increasing the temperature increase the rate constant for backward and forward reaction in equal ratio​

Answer 1

Answer:

B) as it increases only the forward rate not the reverse rate.

Explanation:

A)

the catalyst reduces the energy barrier by providing an alternative pathway.

B)

Catalysts increase the forward rate, while reducing the reverse rate.

C)

When temperature increases, both rates (forward and reverse) increase but the rate of the endothermic reaction increases more! Equilbrium shifts in the endothermic direction.

Same for D.

Hence, the only one oreect option is B.
