Assertion: Silver bromide decomposition is used in black and white photography.
Reason: Light provides energy for this exothermic reaction.
(a) Both A and R are true and R is the correct explanation of A
(b) Both A and R are true and R is not the correct explanation of A
(c) A is true but R is false
(d) A is False but R is true
Solution:
Exothermic reaction is the reaction in which heat is released while endothermic reaction is the reaction in which heat is added up.
In this decomposition reaction, energy is added in the form of light, which indicates it is endothermic reaction.
So, A is true, R is false.
Exothermic reaction is the reaction in which heat is released while endothermic reaction is the reaction in which heat is added up.
In this decomposition reaction, energy is added in the form of light, which indicates it is endothermic reaction.
So, A is true, R is false.
