WebThe reaction quotient, Q, is a measure of the relative amounts of reactants and products during a chemical reaction at a given point in time. By comparing the value of Q to the equilibrium constant, K eq, for the reaction, we can determine whether the forward reaction or reverse reaction will be favored. Take the following generic equation: aA ... WebQ can be used to determine which direction a reaction will shift to reach equilibrium. If K > Q, a reaction will proceed forward, converting reactants into products. If K < Q, the reaction will proceed in the reverse direction, converting products into reactants. If Q = K then the system is already at equilibrium. challenge positionWeb36K views 7 years ago videos Chemistry Calculating enthalpy using delta H = q/# of moles where q is often found via mCdeltaT, enthalpy of formation values, Hess's law and bond energies... happy frog quotes fnaf
