A) Become 1/9 of 740 mm
B) Become half of 740 mm
C) Remains unchanged
D) Become double of 740 mm
Correct Answer: B
Solution :
According to Dalton's law of partial pressure as number of moles of \[{{O}_{2}}\] and \[{{H}_{2}}\]are same. \[\Rightarrow P{{o}_{2}}={{p}_{{{H}_{2}}}}=p\] Total pressure \[P=P{{o}_{2}}+{{p}_{{{H}_{2}}}}+2p\] \[p=\frac{P}{2}=\frac{740\,mm}{2}\] = 370 mm The pressure of \[{{H}_{2}}\] gas is 370 mm.
