Question

For which value of equilibrium constant, reaction proceeds nearly to completion
k=0.1
K=1
K = 10
K= 1000​

Answer 1

Answer:

● When equilibrium constant value is equal to 1 then the reaction proceeds nearly to completion.

Answer 2

Answer:

Out of the given options, for the value of the equilibrium constant, $K = 1000$, the reaction proceeds close to completion.

Therefore, option d) $K = 1000$ is correct.

Explanation:

Let the equilibrium constant for the reaction given below = $K$

The reaction:

• $aR \rightleftharpoons bP$

Here, a and b are constants of the reactants and the products respectively.

And R is the reactant and P is the product.

As we know, the reaction will proceed nearly to completion, when the amount of the products is much larger than the amount of the reactants.

As we know,

• The equilibrium constant is the ratio of the amount of the product and the amount of the reactant.

Therefore,

• $K = \frac{[P]^{b} }{[R]^{a} }$

As we can see in the above formula, the equilibrium constant is directly proportional to the amount of the product.

• The larger the value of the equilibrium constant, the larger will be the amount of the product.
• Also, the reaction will proceed in the forward direction, i.e., the reaction proceeds nearly to completion.

Out of the given options, the larger value of the equilibrium constant is $1000$.

Hence, for the value of the equilibrium constant, $K = 1000$, the reaction proceeds nearly to completion.
