Using Le-Chatelier's principle, predict which conditions of temperature and pressure would give high yield of products in the following reactions:
(i) `CO_2(g) + H_2(g) hArr H_2O(g) + CO(g) " " ;DeltaH =+41 kJ`
(ii) `2SO_2(g) + O_2(g) hArr 2SO_3(g) " " ;DeltaH=-198 kJ`
(iii) `N_2(g)+O_2(g) hArr 2NO(g) " " ;DeltaH =175 kJ`

Calculate in kJ for the following reaction : C(g) + O_(2)(g) rarr CO_(2)(g) Given that, H_(2)O(g) + C(g) + H_(2)(g) , Delta H = +131 kJ CO(g) + 1/2 O_(2)(g) rarr CO_(2)(g), " " Delta H = -242 kJ H_(2)(g) + 1/2 O_(2)(g) rarr H_(2)O(g), " "DeltaH = -242 kJ

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

The yield of product in the reaction, A_(2)(g)+2B(g) hArr C(g)+Q KJ would be higher at:

In which of the following reactions, increase in temperature as well as decrease in pressure shift the equilibrium towards the forward direction : (i) PCl_5(g) hArr PCl_3(g) + Cl_2(g) " " DeltaH =+ve (ii) N_2(g) + O_2(g) hArr 2NO(g) " " DeltaH =+ve (iii) 2SO_2(g) + O_2(g) hArr 2SO_3(g) " " DeltaH =-ve (iv) N_2O_4 (g) hArr 2NO_2(g) " " DeltaH =+ve

What will be the effect of increased pressure on the following equilibria : (i) N_2(g) + 3H_2(g) hArr 2NH_3(g) (b) N_2O_4(g) hArr 2NO_2(g) (iii) 2SO_2(g) + O_2(g) hArr 2SO_3(g) (iv) H_2(g) +I_2(g) hArr 2HI(g)

Predict the effect of compression on the following equilibrium reaction: CH_4(g) + H_2O(g) hArr CO(g) +3H_2(g)
