Given the equilibrium system
`NH_(4)Cl(s)hArr NH_(4)^(+)(aq)+Cl^(-)(aq) (DeltaH=+"3.5 kcal/mol").`
What change will shift the equilibrium to the right?

A

Increase in temperature

B

Decrease in temperature

C

Addition of `NaCl` crystals

D

Addition of `NH_4OH` solution

Text Solution

Verified by Experts

The correct Answer is:
A
`to` In, endothermic reaction, on increasing T, reaction moves in forward direction.
`to` There is no effect of addition of solid component on equilibrium.
`to` On adding `NH_(4)OH, NH_(4)^(+)` concentration increases, due to which reaction moves to left side.

Consider the chemical reaction: underset(("Green solution"))(Ni^(2+)(aq))+6NH_(3)(aq) hArr underset(("Blue solution"))([Ni(NH_(3))_(6)]^(2+)) (aq) When H^(o+)(aq) is added, the colour green is favoured. Use one or more of the following interpretations to answer the questions: i. Some unreacted Ni^(2+)(aq) is present in the solution at equilibrium ii. Some unreacted NH_(3)(aq) is present in the solution at equilibrium iii. The colour change indicates new equilibrium conditions with reduced [Ni(NH_(3))_(6)]^(2+)(aq) iv. The colour change indicates new equilibrium conditions with increased [Ni(NH_(3))_(6)]^(2+)(aq) . The deepening of blue colour on addition of more NH_(3)(aq) supports interpretation(s).
