C6H14(l)->C6H14(g) ->6CO2(g) + 7H2O(g) ->6CO2(g) + 7H2O(l)
Hexane is a liquid at room temp. It can be converted into carbon dioxide and water through the above processes. There are 3 steps. Steps 2 & 3 are exothermic, right? I think step 2
C6H14(g)-„ł6CO2(g) + 7H2O(g) is something like combustion so it is exothermic.Please help.
