We are being asked to determine the reaction quotient for the reaction below given the concentrations of each species.

2 NO2(g)  N2O4(g)

The reaction quotient, Q, can be calculated like an equilibrium constant with the formula shown below:

$\overline{){\mathbf{Q}}{\mathbf{=}}\frac{\mathbf{products}}{\mathbf{reactants}}}$

Let’s calculate the Reaction Quotient (Q) using the given concentrations:
