2. The rate constant of a first order reaction is 66 s-1. What is the rate constant in units of minutes

3960/min

Explanation:

The rate constant is expressed in seconds (s): 66 s⁻¹ = 66/s

We know that: 1 min = 60 s

Conversion factor = 60 s/1 min

We multiply the rate constant by the conversion factor to obtain the rate constant expressed in units of minutes:

rate constant = 66/s x 60 s/1 min = 3960/min
