Answer 1

hola mate..!!

⇔Answer:-

Option B

⇔Reason:

=> As we know, that Energy is absorbed to break bonds, and energy is evolved as bonds are made. In some reactions the energy that is required to break bonds is larger than the energy evolved on making new bonds, and the net result is the absorption of energy.....
