Question

If the rate constant for the forward reaction in N2O4(g)Colorless⇋2NO2(g)Brown is larger than the rate constant for the reverse reaction, will the constant in [NO2]2[N2O4]=kfkr be greater than 1 or smaller than 1?

Answer 1

Answer:

$\dfrac{k_{f}}{k_{r}} > 1$

Explanation:

  N₂O₄(g) ⇋ 2NO₂(g)

colourless     brown

$\rm N_{2}O_{4}\xrightarrow[k_{\text{r}}]{k_{\text{f}}}2NO\\K_{\text{eq }} = \dfrac{k_{f}}{k_{r}}\\\\\text{If }k_{f} > k_{r}, K_{\text{eq }} > 1$
