Which of the following statements is incorrect with respect to the use of a catalyst in the reversible reaction?
The catalyst increases the rate of only the forward reaction.
The statement in Option 1 is incorrect because a catalyst increases the rates of both the forward and backward reactions in a reversible reaction. It does not selectively increase the rate of only one reaction. The catalyst works by lowering the activation energy for both directions of the reaction, speeding up the reaction in both directions equally. Hence, the correct answer is Option 1.
A reaction takes 30 minutes to complete 50% of the reaction and takes 45 minutes to complete 75% of the reaction. The order of the reaction is:
Ferric oxide in blast furnace's upper half is mainly reduced by:
If time taken for a first-order reaction to get 90% complete is 24 min, its t99.9% will be:
