Question

In the Wilhelmey equation of a first order reaction $c_t=c_0{e}^{-kt}$. If the initial concentration $c_0$ is increased m times, then:

• A. The value of k will increase m times
• B. The value of k will decrease m times
• C. The value of k will remain unchanged
• D. None of these

Answer 1

Answer: (C)

The value of k will remain unchanged

First order reaction is independent of $c_0$, Hence, k is constant.
