Explain the following with the help of Le-Chatelier's principle:
(i)Ice melts when pressure is applied on it.
(ii) Pressure has no effect on the reaction
`H_2(g) + I_2(g) hArr 2HI(g) , DeltaH`=-ve

For the reaction N_(2)(g) + 3H_(2)(g) hArr 2NH_(3)(g), DeltaH=?

Account for the following : (i) Addition of CI_(2) to the following equilibrium mixture increases the temperature of the system SO_(2) CI_(2) + " heat " hArr SO_(2) + CI_(2) (ii) Ice melts when pressure is applied on it. (iii) Pressure has no effect on the reaction H_(2) (g) +CI_(2) (g) hArr 2HCI (g)

Do you expect DeltaS to be +ve, -ve , or zero for the reaction H_(2)(g) +I_(2)(g) hArr 2HI(g)

The equilibrium constant K_(p) for the reaction H_(2)(g)+I_(2)(g) hArr 2HI(g) changes if:

If pressure applied on the following reaction becomes four times H_2(g) + l_2(g) ⇋ 2HI(g) then

On the basis of Le Chatelier principle explain how temperature and pressure can be adjusted to increase the yield of ammonia int he following reaction. N_2(g)+3H_2(g)hArr2NH_3(g), DeltaH=-92.38KJ Mol^(-1) What will be the effect of addition of argon to the avove mixture at cosntant volume ?

Using Le-Chatelier's principle, predict the effect of (i) decreasing the temperature (ii)increasing the temperature on each of the following : (a) N_2(g) + 3H_2(g) hArr 2NH_3(g) " " DeltaH =-ve (b) N_2(g) +O_2(g) hArr 2NO(g) " " DeltaH =+ve
