In the reaction A + B rArr C + D, what will happen to the equilibrium

1.	In the reaction A + B rArr C + D, what will happen to the equilibrium is concentration of A is increased ? The equilibrium constant for a reaction is 2 xx 10^(-23) at 25^@C and 2 xx 10^(-2) at 50^(@). Is the reaction endothermic or exothermic ? (c) Mention at least three ways by which the concetration of SO_(3) can be increased in the following reaction in a state of equilibrium. 2SO_(2)(g) + O_(2)(g) hArr (g)
Answer» Solution :The reaction will shift in the forward direction. (b) ENDOTHERMIC (c) (i) INCREASING concentration of `SO_2` (ii) incrasing PRESSURE. (iii) increasing concentration of oxygen.
