Answer

Brief Explanations:

Increasing temperature provides more kinetic energy to reactant molecules, increasing the frequency of effective collisions and thus the reaction - rate. Increasing pressure for a gas - phase reaction like this one (where there are fewer moles of products than reactants) brings the reactant molecules closer together, also increasing the frequency of collisions and the reaction rate.

Answer:

increase temperature and increase pressure
