1. PREMIERE QUESTION

2. c) Determine the final pressure in the vessel in mbars d) Assuming that CO 2 behaves nonideally, determine its partial pressure at the end of combustion( for CO 2 the real gas constants a=3,59 ; b= 0,0427 ), what is the deviation rate from ideal gas law? Compare both results and give the reason for the difference e) If 26,88 g of O 2 had been additionally pumped into the container before the combustion, what would be the mole fraction of O 2 after combustion and what would become the final pressure? (C=12, H=1, O=16)

3. Example : Equal moles of below indicated gases at equal volumes were mixed at 0°C. Which of them would you expect to behave most ideally? Explain your reasoning by making calculation! GASab Cl 2 6,490,0562 CO 2 3,590,0427 NH 3 4,170,0371 O2O2 1,360,0318 N2N2 1,390,0391
