Passage / Comprehension
Chemical explosions are characterised by the instantaneous release of large quantities of hot gases, which set up a shock wave of enormous pressure and velocity. Explosion of a compound X releases four gases A, B, C and D.
n X a A(g) + b B(g) + c C(g) + d D(g)
Assume that the explosion of 1 mol of X releases gases with a temperature of 2727°C and a volume of 3.0 l at 410 atm pressure. (R = 0.0821 l-atm/K-mol)
How many moles of hot gases are released by the explosion of 0.02 mole of X?
Options:
Answer:
C
Solution:
Per mole of X, n = PV/RT = 410 × 3.0/(0.0821 × 3000) ≈ 5.0 mol of gas. For 0.02 mol: 5.0 × 0.02 = 0.1 mol. Hence (c).
