Question

A very large value of Kc indicates that reactants are __________.

(very stable, unstable, moderately stable)​

Answer 1

Dear Student,

◆ Answer -

A very large value of Kc indicates that reactants are unstable.

● Explanation -

Kc is the ratio of concentration of products to concentration of reactants at equilibrium.

A very large value of Kc indicates that reaction will proceed forward making the reactants unstable and products stable.

Thanks dear. Hope this is helpful to you...

Answer 2

A very large value of Kc indicates that reactants are unstable.

Explanation:  

• Kc is equivalent constant of a reaction. It is a ratio between the ‘concentrations of the products’ in a reaction to the concentration of reactants in a reaction.  

• A very large value of KC indicates that the reactance are relatively less in amount than the products present.  

• As a result the products are formed due to the unstability of the reactants present.  

• On the other hand if the KC value is low that means the reactants are very stable.
