What happens when pressure is increased in the following equilibrium rection
(i) N2O4(g)=2NO2(g)
(ii) H2(g)+I2(g)=2HI(g)
According to lechatlier principle the pressure in a system increases, the equilibrium will shift to favor the side of the reaction that involves fewer moles of gas.
Thus,
Part -I
N2O4(g)→2NO2(g)
Reaction move in backward direction.
Part -II
H2(g)+I2(g)→2HI(g)
No effect due to same no. of moles in reactant and product.
