Plz solve these two first time we
Dear student
We knew that
Zero Order reactions are not depends upon the concentrations of reactants and products.
Half life period is the time where the concentration of the reactants are reduced to the half of the initial concentration.
Given that,
Initial amount of reactant = 40 g
After 10 min (half life period) concentration of the reactant = 20 g
Therefore, 20 g of the reactant is consumed in 10 min. Hence 40 g of reactant is consumed in 20 min.
Hence, concentration of the reactant after 20 min = 0
so, option (4) is correct.
