Estimate the ΔH_{reaction}reaction for the reaction shown below using data from table 9.3. Show calculations and answer should be in units of kJ/mol and reported to the ones place.
For the reaction
We have,
Hreaction
=
Bond energy of

= [4(C-H) + (C=C) + (O = O)] - [ 4(C-H) + 2(C = O)] KJmol-1
= [ (4 x 412) + 612 + 497] - [ (4 x 412) + (2 x 743) ] kJmol-1
= [1648 + 612 + 497] - [1648 + 1486] kJmol-1
= 2757 - 3134= -377 kJmol-1
