Answer:
- 484 KJ/mol
Explanation:
The reaction equation is;
CH4(g) + F2 (g) ------> CH3F(g) + HF(g)
The enthalpy of the reaction can be calculated from bond energies using the formula;
ΔHreaction = Bond energy of reactants - bond energy of products
or
ΔHreaction = Bonds broken - bonds formed
[4(413) + 1(155) - 3(413) + 1(485) + 1(567)]
[(1652 + 155) - (1239 + 485 + 567)]
[1807 - 2291]
= - 484 KJ/mol
The actions are that some people will or may not pay forthe gas if it costs that much!
I got the same answer as you so try picking the answer that is closest to the answer you got sorry i couldn't help much
