In an industrial gas scrubber, the gaseous reaction between nitrogen monoxide and oxygen is monitored:
\
2\\text{NO}(\\text{g}) + \\text{O}_2(\\text{g}) \\rightarrow 2\\text{NO}_2(\\text{g}){\char"24}$ Engineers find that increasing the pressure of the reactant gases in the reaction chamber, while keeping the temperature constant, significantly increases the rate of production of nitrogen dioxide.Explain, in terms of particles and collisions, why increasing the pressure of gaseous reactants increases the rate of reaction.
