(i) Reaction of water with quick lime

(ii) Dilution of an acid

(iii) Evaporation of water

(a) (i) and (ii)        (b) (ii) and (iii)

(c) (i) and (iv)        (d) (iii) and (iv)

Answers (1)

Ans. (a)

When water reacts with water and acid it releases enormous amount of heat. Similarly, when water reacts with quick lime it releases a lot of heat.

When water reacts with quick lime, calcium hydroxide is formed along with release of heat. Hence, it is an exothermic reaction.

Dilution of an acid – Highly exothermic

Evaporation of water and sublimation of camphor are examples of endothermic reactions.
