The volume change associated with a chemical reaction is often approximated as being directly proportional to the change in the number of moles of gas (moles of gaseous products - moles of gaseous reactants) .The combustion of methanol at 25°C and 1 atm releases about 1453 kJ of heat.Which of the following correctly describes the relationship between vE and H? 2 CH3OH(
) + 3 O2(g) 2 CO2(g) + 4 H2O(
)
A) " H < -1453 kJ, E = -1453 kJ"
B) " H > -1453 kJ, E = -1453 kJ"
C) " H = -1453 kJ, E > -1453 kJ"
D) " H = -1453 kJ, E < -1453 kJ"
E) " H = -1453 kJ, E = -1453 kJ"
