1.

Match the entries listed in Column I with appropriate entries listed in Column II.

Answer» Correct Answer - A::B::C::D
(A) Increae in pressure shifts the equlibrium in te direaction where lesser no. of gaseous moles are present. `(Deltang=n_(p)-n_(r)=2-4=-2)`
(B) Increase in temperature shifts the equlibrium in the direction of endothermic reaction.
`(Deltang=n_(p)-n_(r)=3-3=0,` hence pressure is unchanged)
(C) Decrease in pressure shifts the equlibrium in the direaction where larger no. of gaseous moles are present.
`(Deltang=n_(p)-n_(r)=2-1=1)`
(D) No gaseous moles present hence no effect of pressure.
