- Consider a reaction with an Keq ~ 1.0 * 10-55 , when the reaction reaches equilibrium no product Is formed disagree.
Explanation : If equilibrium constant Is very less then it means that reaction is slow. If a reaction reaches equilibrium then some amount of product has to form.
2) Initially when a reaction begins, and reactant converts to product but before the reaction reaches equilibrium , the reaction quotient Q is decreasing Disagree.
Explanation: It depends upon the equilibrium constant (K). It can be decreasing or increasing depending upon K.
3. For , an exothermic reaction , a decrease In temperature leads to an increase in Keq for the reaction at new temperature Agree.
Explanation: in exothermic reaction delta H is negative so if we decrease the temperature, the reaction will be favoured.

Select all of the correct statements about reaction quotients and equilibrium constants from the choices below. A reaction quotient equals the equilibrium constant at equilibrium. In a reacting mixture K is the ratio of product to reactant concentrations. As a reaction progresses backwards toward equilibrium K is the lowest value Q attains. K changes as temperature changes, but is independent of concentrations. A reaction quotient is the same as an equilibrium constant. As a reaction progresses...
