1 Mole of propane `(C_3H_8)` on combustion at STP gives 'A' kilo joules of heat energy. Calculate the heat liberated when 2.4 ltrs of propane on combustion at STP.

1 mole of propane (C_3H_8) on combustion at STP gives ‘A’ kilo Jules of heat energy. calculate the heat liberated when 2.4 litres of propane on combustion at STP.

Change in enthalpy and change in internal energy are state functions. The value of DeltaH, DeltaU can be determined by using Kirchoff's equation. I mole of naphthalene (C_(10)H_(8)) was burnt is oxygen gas at 25^(@)C at constant volume. The heat evolved was found to be 5138.8kJ. Calculate the heat of reaction at constant pressure

Enthalpy of combustion of carbon to CO_(2) is -393.5 kJ mol^(-1). Calculate the heat released upon formation of 35.2 g of CO_(2) from carbon and dioxygen gas.

The volume of oxygen required at STP for the complete combustion of 2.2 g of propane

3L Mixture of propane and butane on complete combustion at 298K and 1atm gave 10L CO_2. Calculate the composition of gas

Given below are some standard heats of reaction (at constant pressure) (A) Heat of formation of water = -68.3 kcal (B) Heat of combustion of acetylene = - 310.6 kcal (C ) Heat of combustion of ethylene = - 337.2 kcal Calculating the heat of reaction for the hydrogenation of acetylene at constant pressure and at constant volume (at 25^(@)C )
