Question

In an equilibrium reaction, the concentration of reactants decreases initially and then becomes constant.
If true enter 1, if false enter 0.

Answer 1

In an equilibrium reaction, the concentration of reactants decreases initially and then becomes constant. Initially more and more reactants are converted to products. The rate of forward reaction is much higher than the rate of the backward reaction. Due to this, the concentration of reactants decreases with progress of reaction. This continues till an equilibrium is established at which the rates of forward and backward reactions are equal. Whatever amount of reactants are consumed in the forward reaction, an equivalent amount is formed in the reverse reaction. The concentration of the reactants becomes constant.
