Question

Two bulbs A and B of equal volumes connected
through stopcock (kept open) contained 0.7 mol of
H2 gas at pressure of 0.5 atm and 27°C. The bulb A
is heated to 127°C keeping bulb B at 27°C. Calculate
final pressure and molar distribution of H2 in two
bulbs.
No spamming please....if you f.in don't know the answer please just don't answer with usless things... enough of those bul.shts... sorry for being this much rude...not for good people who are really here to help

Answer 1

Answer:

P2 = 400 x .5 /300 =2/3

no of moles = 14/15

final pressure= 0.571 moles

Explanation:

P is directly proportional to the T.

Use the formula P1/P2 = T1/T2

Final Pressure: Original pressure x Original Volume = Final pressure x Final Volume
