Question

How many liters of oxygen reacted at 21 degrees celcius and101kPa would be required to produce 1000kJ by this reaction? P4(s) + 5O2(l) --->P4O10(s)                                     H = -696.4kJ Please show all your work and explain!!
Will rate good!

Explanation / Answer

      P4(s) +5O2(l) --->P4O10(s)         H = -696.4kJ         5 moles of oxygenreacts to release 696.4 kJ of energy.         Number ofmoles of oxygen required to produce 1000 kJ   = 5 *1000 /696.4                                                                                                      = 7.17 moles                   Pressure = 101 kPa = 0.996 atm                  temperature = 21oC =   294 K               let the volume be V litres.              PV = nRT            0.996 atm * V = 7.17 * 0.0821 L.atm/mol.K * 294 K                        volume = 173.7 L
