The total pressure of the mixture is 65.5 kPa.
According to Dalton's Law of Partial Pressure,
The partial pressure of gas = Mole fraction of gas × Total pressure
Total Pressure = Sum of all the gases partial pressures
The number of moles of methane is,
= 0.021 mols
The moles of methane are 0.021 mols.
The number of moles of the argon,
= 0.003 mols
The number of moles of argon is 0.003 mols.
The number of moles of nitrogen is,
= 0.010 mols
The number of moles of nitrogen is 0.010 mols.
The total number of moles is,
= 0.021 + 0.003 + 0.010
= 0.034 mols
= 0.29
= 65.5 kPa
Therefore, the total pressure of the mixture is 65.5 kPa.

Explanation:
A chemical equilibrium is defined as the state of reaction in which the rate of forward reaction is equal to the rate of backward reaction.
When Q > , then it means that the reaction is proceeding in the backward reaction. Whereas if Q <
, then it means that the reaction is proceeding in the forward direction. Hence, formation of products will be favored.
On the other hand, if Q = , then it means reaction is at equilibrium.
At equilibrium, it is not necessary that the concentrations of products divided by the concentrations of reactants equals one.
Thus, we can conclude that the statement for a chemical system at equilibrium, the forward and reverse rates of reaction are equal, is correct.
