A catalyst sample of $0.0040 mol$ of active sites produces $3.1 mol$ of product in $45 min$ at constant rate. Calculate the turnover frequency in $mi n^{- 1}$ (mol of product per mol of active sites per minute), to the nearest integer.

Numerical answer type, answer in min^-1, tolerance 1.

Answer: 17 min^-1

TON

= 3.1/0.0040 = 775

for the whole run. Dividing by

45 min

gives TOF

= 775/45 = 17.22 mi n^{- 1}

, about 17.
