Given the following reaction:
CH3CH2OH(l)+3O2(g)→2CO2(g)+3H2O(l)CH3CH2OH(l)+3O2(g)→2CO2(g)+3H2O(l)
∆H = –2200 kJ/mol CH3CH2OHCH3CH2OH
a) This reaction is...
Select one or more:
a. exothermic
b. endothermic
If the enthalpy change is positive ( menas greater than 0) then system will absorb heat and called endothermic process.
As enthalpy is negitive so system will release energy and hence the recation is exothermic.
Hence option a is correct
