4. A container with a fixed volume of 1 liter contains: 0.0010 moles of acetylene (C2H2),0.00025 moles of O2, and 0.5 moles of Argon (Ar) The temperature of the gas is 25C. A spark is applied, such that the following reaction occurs: C2H2+5/2O22CO2+H2Oq=?(inkJ) The temperature of the gas after the reaction is complete is 235C. An ideal gas assumes gasses are simple particles like Ne, which can only move through space (i.e. change Cv. However, as we showed in lecture, Cr=Cv+R applies to any gas for which PV=nRT (and most real gasses do obey PV=nRT to high accuracy). This means that Cr=3/2R applies only to monatomic gasses such as Ne or Ar. However, Cp=C8+R applies to most gasses. (Assume that Ar behaves as an ideal gas, and that no heat is lost to the container or surroundings.) 4.1. What is the heat, q, released in the above reaction (in kJ)? 4.2. If the above reaction were done in a 2 liter container instead of a 1 liter container, using identical numbers of moles of C2H2,O2 and Ar, at an initial temperature of 25C, what would be the final temperature of the gas? 4.3. If the above reaction were done at constant pressure instead of constant volume, using identical amounts of substances and starting at a volume of 1 liter and a temperature of 25C, what would be the final temperature of the gas
