Unformatted text preview: r. Chapter 6.4 Applications of the Equilibrium Constant - The value of the equilibrium constant can be used to decide on the feasibility of a reaction! Consider with The amount of NO that can be produced under these conditions is extremely small. Simply speaking, the N2/O2 mixture “will not react”. In this situation it “will react” Reaction Quotient (Q): - Initially (= when the reaction starts), pressures can have any value. They only depend on the person who sets up the experiment. - We define the reaction quotient Q; it looks just like the equilibrium constant; The difference is that for; … K we use the partial pressures (or concentrations) at equilibrium … Q we use the initial partial pressures (or concentrations) 1. If Q = K the reaction is at equilibrium, so the amounts of reactant and product remain unchanged. 2. If Q > K there is “too much product”; the reaction will proceed from right to...
