Question

What is the effect of addition of h2 and removal of co?

Answer 1

(a) According to Le Chatelier’s principle, on addition of H2, the equilibrium of the given reaction will shift in the forward direction

(b) On removing CO, the equilibrium will shift in the backward direction. 

Answer 2

■addition of h2 in unsaturated hydrocarbon is called hydrogenation / addition reaction / reduction

example :

C2H4 -----(by the help of catalyst such as nickel and palladium ) ------> C2H6

■if co2 is released during a reaction then it turns the lime water milky

example of removal of Co2 ...

Na2CO3 + HCl ------> NaCl + Co2 + H20
