Which change favors the products in this reversible reaction n2o4(g)+58 kj 2no2 (g)?

According to Le Chatelier's Principle, the position of equilibrium moves to counteract the change, the position of equilibrium will move so that the concentration of products of chemical reaction increase, if:

1) increase temperature, because this endothermic reaction.

2) increase concentration of reactant.

3) decrease pressure of the system, so reaction moves to direction where is more molecules.
