Answer : The correct option for blank 1 is, Forward and Backward direction
.
The correct option for blank 2 is, Reach equilibrium
.
Explanation :
- Reversible reaction : It is a reaction in which two or more reactants react together to give products and these products react with other product to form reactants.
It occurs in both the directions at the same time, forward and backward direction.
- Irreversible reaction : It is a reaction in which reactants react together to give a product but it can not revert back into the reactants.
It occurs in forward direction only.
- Equilibrium reaction : It is a reaction in which the rate of forward reaction is equal to the rate of backward reaction.
- Completion reaction : It is a reaction in which the reactants react together to give products. when the reaction goes to completion theta means all the reactants are used up and you have only products in the reaction.
