Problem

For an isothermal reaction

\text{A}(g) \rightleftharpoons \text{B}(g)

at 350 K, the uncatalyzed rate constants are

k_{\text{f}}=1.0\times10^{-3}\,\text{s}^{-1}

and

k_{\text{r}}=5.0\times10^{-4}\,\text{s}^{-1}

. A suitable catalyst increases each rate constant by exactly a factor of 100. What is the numerical value of the equilibrium constant before and after the catalyst is added? a) Before:

2.0

; After:

200

b) Before:

0.50

; After:

0.50

c) Before:

2.0

; After:

2.0

d) Before:

2.0

; After:

0.020
