Heat of combustion of ethyne

Assignment Help Chemistry
Reference no: EM131118818

An oxy-acetylene welding torch uses ethyne (acetylene) at the rate of 500 mL per minute, measured at STP. The reaction is described by:

2C2H2(g) + 5O2(g) ® 4CO2(g) + 2H2O(l); DH = -2599 kJ mol-1

What is the heat of combustion of ethyne in kJ mol-1 and kJ g-1?
