Question

2. Which of the following are exothermic reactions?
© Evaporation of water
(m) Dilution of H2SO,
(i) Reaction of water with quick lime
(iv) Sublimation of crystalline camphor
A. (w) and (iv) B. O) and (v) C. O) and (H) D.) and (w)​

Answer 1

Answer:

When water reacts with quick lime, calcium hydroxide is formed along with release of heat. Thus, it is an exothermic reaction. The process of diluting a concentrated acid is a highly exothermic process. Evaporation of water and sublimation of camphor are examples of endothermic reactions.

Answer 2

Answer:

Dilution of H2So

reaction of water with quick lime
