Target Reaction: 2CO2(g) + H2O(g) → C 2H2(g) + 5/2O2(g) Step Reactions: C2H2(g) + 2H2(g) → C2H6(g) ΔH = -94.5kJ H2O(g) → H2(g) + 1/2O2 (g) ΔH = 71.2 kJ 2C2H6(g) + 7O2(g) → 4CO2(g) + 6H2O(g) ΔH =-566 kJ

What is the temperature in kelvin of a gas if it is allowed to expand from 1.50 l to 4.50 l? the initial temperature is 10.0°c and pressure is constant throughout the change. which equation should you use? t2= v2/v1 t1 what is the final temperature? ⇒ 849 k these are the answers.
