In a closed flask of 5 l, 1.0 g H2 is heated from 300 to 600 K. Which statement is not correct?
Options:
Answer:
C
Solution:
The flask is closed and rigid, so n and V are fixed. Heating 300 → 600 K: P = nRT/V rises, molecular speeds rise so collision rate rises, and average KE = 3/2kT rises. But the amount of gas cannot change in a closed flask — H2 does not dissociate at 600 K — so the number of moles stays constant. Statement (c) is the incorrect one. Confirms Ans (c).
