Answers
Chemical equilibrium is attained in a reversible reaction when the rate of forward reaction is equal to the rate of backward reaction.
Chemical equilibrium is attained in a reversible reaction carried in a close container and is of dynamic nature. The value of equilibrium constant may be expressed either as
and the two are related to each other as : <br>
<br> Free energy change
at equilibrium point is zero. The value of equilibrium constant gives the extent to which a particular reation has proceeded to attain the equilibrium . Its value gets reversed if the reaction is reversed and becomes the square root of the initial value if the reaction is divided by 2. <br> when the two reactants A and B are mixed to give products C and D , the reaction quotient Q at initial stage of the reaction:
