Problem

A solid catalyst provides

3.0\times10^{-4}\,\text{mol}

of active surface sites. When

40\%

of the sites are occupied by reactant A, the surface reaction proceeds with a first‐order rate constant of

0.50\,\text{s}^{-1}

based on occupied sites. What is the initial rate of product formation? a)

1.5\times10^{-4}\,\text{mol}\,\text{s}^{-1}

1.2\times10^{-4}\,\text{mol}\,\text{s}^{-1}

6.0\times10^{-5}\,\text{mol}\,\text{s}^{-1}

9.0\times10^{-5}\,\text{mol}\,\text{s}^{-1}
