Question

A. Whenever a system is not at equilibrium, the relative amounts of reactants and products can be expressed by Q. B. The free energy change of a system is the free energy change at standard state minus the value of RT ln?(Q). C. Equilibrium in a reaction is a balance between the entropy and the enthalpy of the reaction. D. Adding chemical energy to a system at equilibrium will always cause a shift toward either products or reactants. A.

Explanation / Answer

when equilibrium is not achieved ...........   it is denoted by Q ........ when equilibrium is achieved Q becomes K !!!!

adding eneergy to reaction makes it shift in sucj diection such that energy is utilised so the reaction shifts according it is endothermic or exothermic !!!
