Question

Bond dissociation energy of xy x2 and y2 are in the ratio 1 10.5 and formation of xy is minus 200 joule per mole the bond dissociation energy of h2 will be

Answer 1

hey!! the answer will be simply subtract the of enthalpy of reaction of 2XY from the sum of the enthalpy of reaction of X2 and Y2 you will have the answer as +800KJ .

Hope this helps!!
