1.	Consider the following reactions, (a) H_2(g)+ I_2(g)hArr 2HI(g) (b) CaCO_3(s) hArr CaO(s)+ CO_2(g)(c ) S(s) + 3F_2(g) hArr SF_6(g) In each of the above reaction find out whether you have in increase (or)decrease the volume to increase th yield of the product.
Answer» SOLUTION :(a) `H_2(g) + I_2(g) hArr 2HI(g)` In the above equilibrium reaction, volume of gaseous molecules is equal on both sides. So INCREASE or DECREASE the volume will not effect the equilibrium and there will be no change in the yield of product. (b) `underset(0(V))(CaCO_2(s)) hArr underset(0(V))(CaO(s))+ underset(1(V))(CO_2(g))` Volume is greater in product side. By decreasing the PRESSURE, volume willincrease thus, to get more of product `CO_2`, the pressure should be decreased or volumeshould be increased. `S(s) + underset(3V)(3F_2(g)) hArr underset(IV)(SF_6(g))` Volume is lesser in product side. So by increasing the pressure, equilibrium shifts to the product side.
