The following data were obtained from enzymatic oxidation of phenol by phenol oxidase at different phenol concentrations.

$\backslash$table$[[,,,,,,,,,,,],[,10,20,30,50,60,80,90,110,130,140,150],[v(m\frac{g}{h}),5,7\mathrm{.}5,10,12\mathrm{.}5,13\mathrm{.}7,15,15,12\mathrm{.}5,9\mathrm{.}5,7\mathrm{.}5,5\mathrm{.}7]]$

a$.$ What type of inhibition is this?

b$.$ Determine the constants $V_{\text{m}\text{a}\text{x}},K_{m^{\text{'}}},$ and $K_s.$

c$.$ Determine the oxidation rate at $[S]=70m\frac{g}{L}.$
