Which of the following are exothermic processes?(i) Reaction of water with quick lime(ii) Dilution of an acid(iii) Evaporation of water(iv) Sublimation of camphor (crystals)
| (a) (i) and (ii) | (b) (ii) and (iii) |
| (c) (i) and (iv) | (d) (ii) and (iv) |
"
Correct answer: (a) (i) and (ii)
Explanation: Reaction of water with quick lime and dilution of acid releases heat energy. Hence, it is an exothermic reaction.
