Question

write the units of rate constant for a half order reaction

​

Answer 1

Answer:

The units of k depend on the order of the reaction , but the units are never Newtons per metre . As an example , for a frist order reaction ,k has the units of 1/s and for a second order reaction , units of 1/M.s.

Answer 2

Concept introduction:

The amount of time needed for the reactant concentration to drop to half its starting value is known as a reaction's half-life. A first-order reaction's half-life is a constant that is correlated with its rate constant: $t1/2 = 0.693/k$. First-order reactions include those in radioactive decay.

Explanation:

Given that, every rate constant have its unit.

We have to find, units of rate constant for a half order reaction.

According to the question,

The units of rate constant for a half order reaction is $s^{-1}$.

Final Answer:

The units of rate constant for a half order reaction is $s^{-1}$.
