Problem: What are the units for k, the rate constant, in a first order reaction where the time unit is seconds (s)? A. mol/(L•s)B. mol/LC. 1/sD. s•mol/LE. s•L/mol

FREE Expert Solution

To determine the unit of k, we will use the following equation:

k=M-n+1·t-1

n = overall order of the reaction
n = order with respect to A

t = seconds, s
