For reactions having large Kc value, the reaction proceeds to:

Choose an answer

Completion

Equilibrium state

back ward

None of these

At dynamic equilibrium:

Choose an answer

The reactions stops to proceed

The amounts of reactants and products are equal

The speed of the forward is reverse reactions are equal

The reaction can no longer be reversed

When the magnitude of Kc is very large in indicates.

Choose an answer

Reaction never go to completion

Reaction is in equilibrium state

Reaction will complete after some time

Reaction has almost to completion

At dynamic equilibrium state:

Choose an answer

Rate of forward reaction≠ Rate of reverse reaction

Rate of forward reaction > Rate of reverse reaction

Rate of forward reaction = Rate of reverse reaction

Rate of forward reaction < rate of reverse reaction

The forward reaction takes place:

Choose an answer

Right to left

Left to Right

Only to right

Only to left
