With increase in temperature, the equilibrium __________ rises in case of endothermic reaction.
Constant
Conversion
Both A & B
Neither A nor B
✅ The correct answer is option B.
A reaction in which one of the products of reaction acts as a catalyst is called a/an __________ reaction.
Catalytic
Autocatalytic
Photochemical
None of these
✅ The correct answer is option B.
In a reversible reaction, a catalyst increases the rate of forward reaction
Only
To a greater extent than that of the backward reaction
And decreases that of the backward reaction
And the backward reaction equally
✅ The correct answer is option D.
Sum of the powers of the concentration terms in the rate equation is called the __________ of the reaction.
Order
Overall order

None of these
✅ The correct answer is option B.
In a zero order reaction, reactants concentration does not change with time and the
Time for half change is half the time taken for completion of the reaction
Time for half change is independent of the initial concentration
Time for completion of the reaction is independent of the initial concentration
