Question

2.
Heat evolved in the reaction, H2 + Cl2--- 2HCI is -182 kJ. Bond energies of H-H and
CL-Cl are 430 and 242 kJ/mol respectively. The H-Cl bond energy is:
(A) 245 kJ mol
(B) 427 kJ mol
(C) 336 kJ mol
(D) 154 kJ mol​

Answer 1

Answer: potion d is correct

Explanation: cause u knw

Answer 2

Answer:

B) 427 kJ mol

Explanation:

H2+cl2 = 2Hcl + 182KJ

Bond energy of H−H−=430 kJ/mol

'" " " " cl - cl = 242 kJ/mol

consider the bond energyof HCL is x

⇒430+242 = 2x−182kj

⇒2x = 430+242+182

⇒x = 427kJ/mol

hope it helps...
