A scientist mixes 0.50 mol NO 2 with 0.30 mol N 2 O 4 in a 2.0-L

Question:

A scientist mixes 0.50 mol NO₂ with 0.30 mol N₂O₄ in a 2.0-L flask at 418 K. At this temperature, K_c is 0.32 for the reaction of 2 mol NO₂ to form 1 mol N₂O₄. Does a reaction occur to form more NO₂ or more N₂O₄, or is the system at equilibrium?
Strategy

Write the chemical equation and the expression for Q. Evaluate Q from the given concentrations and compare with K_eq to determine the direction of reaction.
