Question

The delta H value for reaction C + 1/2 O2 to give C Oand CO + 1/2 O2 gives you to 100 and 200 kilo joule respectively the heat of reaction for C + O2 gives CO2 will be​

Answer 1

Answer:

Given C + O2 CO2 , ΔHº = -x kJ ....(i)

2CO2 2CO +O2 ΔHº = +y kJ … (ii)

or CO2 CO + 1/2O2, ΔH° = +y/2kJ ...(iii)

By adding eq. (i) and (iii), we get

,

ΔHº = y / 2 - x = kJ
