Let us consider a first order reaction,
A → product
For a first order reaction, the rate of reaction,
where k is the rate constant.
Here, c is the constant of integration.
putting the value of c in equation (i), we get,
ln a – ln(a-x) = kt
Equation (ii) is the required expression.
Unit of k:
From equation (ii) we found that the unit of k depends on the unit of t . The unit of k may be s-1, min-1, h-1, day-1 and so on.
