Answer:
[tex]Q= K_{eq}[/tex]
Explanation:
Equilibrium system: It is defined as that condition when the rate of forward reaction is equal to rate of backward reaction.
It is also defined as that condition concentration of reactantsx and concentrations of products are constant .
Suppose a reaction
[tex]aA+bB\leftrightharpoons cC+dD[/tex]
Equilibrium constant,[tex]K_c=\frac{concentartion\;of\;products}{concentration;of;reactants}[/tex]
Equilibrium constant,[tex]K_c=\frac{C^c\cdot D^d}{A^a\cdot B^b}[/tex]
When the reaction is not in equilibrium then reaction constant
[tex]Q_c=\frac{C^c\cdot D^d}{A^a\cdot B^b}[/tex]
When the reaction is in equilibrium then the equilibrium constant is equal to reaction constant
Hence,[tex] Q = K_c[/tex]
When Q < K then the concentrations of reactants are greater than the concentrations of products.
When Q > K then the concentrations of products are greater than the concentration of reactants.
