Question 1
1 / -0

In which of the following, the reaction proceeds towards completion

A
K = 10³

B
K = 10^-2

C
K = 10

D
K = 1

Solution

Those reaction which have more value of K proceeds towards completion.
Question 2
1 / -0

A reversible chemical reaction having two reactants in equilibrium. If the concentrations of the reactants are doubled, then the equilibrium constant will

A
Also be doubled

B
Be halved

C
Become one-fourth

D
Remain the same

Solution

K_c is a characteristic constant for the given reaction.
Question 3
1 / -0

The equilibrium constant in a reversible reaction at a given temperature

A
Depends on the initial concentration of the reactants

B
Depends on the concentration of the products at equilibrium

C
Does not depend on the initial concentrations

D
It is not characteristic of the reaction

Solution

Equilibrium constant is independent of original concentration of reactant.
Question 4
1 / -0

Pure ammonia is placed in a vessel at temperature where its dissociation constant (α) is appreciable. At equilibrium

A
K_p does not change significantly with pressure

B
α does not change with pressure

C
Concentration of NH₃ does not change with pressure

D
Concentration of H₂ is less than that of N₂

Solution

K_p is constant and does not change with pressure.
