Question

driive an expression for rate contant of zero order reaction​

Answer 1

Here's your answer ✌...

Zero order reaction : A reaction is said to be of zero order if the rate is independent of the concentration of the reactants, that means the rate is directly proportional to the zeroth power of the concentration of the reactants.

For the reaction

If the reaction is zero order, then

or,

where, k is the rate constant.

Now integrating both sides, we get

          .....(1)

where, C is the constant of integration

At t = 0, the concentration of the reactant , where is the initial concentration of the reactant.

Therefore,

Now substituting the value of 'C' in the equation (1), we get

This is the expression for the rate constant of zero order reaction.
