The following volume-temperature plots were made at different values of constant pressure while the number of moles of gas in each experiment remained the same. Which plot represents measurements at the highest pressure? (3 pt) (a) A (b) B (c) C (d) D (e) they are all at the same pressure 12. Which of the following concerning the ideal gas law is/are true? (3 pt) ctly proportional to volume when temperature and moles of gas are held constant. 2 Pressure is directly 3.Volume is inverse proportional to moles of gas when temperature and volume are held constant. proportional to temperature when the pressure and moles of gas are held constant. A)I only (8) 2 only (C)3only (D) 1 and 2 only 13. What volume (A) 20L (8) 0.8L ((C)4L (D)1L (E) 16 L (E) 2 and 3 only of sulfur trioxide gas, SOs, has the same number of atoms as 4 L of helium gas at the same temperature and pressdre? (3 pt) PV 2 14. Which conditions of P, T, and n, respectively, are most ideal? (3 pt) A) low P, low T, low n (8) high P, low T, high n (C) low P, high T, high n (o) Iow P,high T, low n 15. In which of the following reactions will the pressure increase upon completion of the reaction at constant temperature? (3 pt (B) 2NOgNG(g) ? 2NO2 (g)

Explanation / Answer

Ans 10 : E) 53 L

Using the ideal gas law , pV = nRT , we get the relation as :

p1V1 = p2V2

putting all the values we get :

1.0 x 37 = 0.70 x V

V = 53 L
