Use this information to complete the following table.

Suppose a $5\mathrm{.}0$ L reaction vessel is filled with $0\mathrm{.}43$ mol of NO$2$ and $0\mathrm{.}43$ mol of CO$.$ What can you say about the composition of the mixture in the vessel at equilibrium?

There will be very little NO$2$ and CO$.$

There will be very little NO and CO$2.$

Neither of the above is true.
