Question

Which of the following statements are true for a zero order reaction? A) The reaction proceeds with a constant rate throughout B) The ratio of times required for half change and 3/4th change is 1:2 C) The rate of reaction and rate constant have the same units D) A plot of rate v/s time is a straight line parallel to rate-axis

Answer 1

Answer:

option c is correct

Explanation:

Answer 2

The rate of reaction and rate constant have the same units.

A plot of rate v/s time is a straight line parallel to rate-axis.

Step-by-step explanation:

zero-order reaction is the reaction in which the rate is independent on the concentrations of the reactions.

• The rates of these reactions do not vary with increasing or decreasing reactants concentrations. So, the rate of the reaction is equal to the rate constant,  k , of that reaction.

For zero-order reaction

                    $t_\frac{1}{2} = \frac{a}{2k}$

• ​We can see that the half-life depends on the initial concentration of reactant $(a)$ and the rate constant.

• If a graph is drawn between time and rate it will be a straight line parallel to rate-axis..

• The unit of rate constant is $molL^{-1} time^{-1}1.$
