Question
Water decomposes to O2 and H2 under suitable conditions as represented by the equation below:
\[\ce{2H2O -> 2H2 + O2}\]
The 2500 cm3 of H2 is subjected to `2 1/2` times increase in pressure (temp. remaining constant). What volume will H2 now occupy?

Solution
P1 = x suppose
P2 = x + `5/2`x = `7/2`x
V1 = 2500 cm3
V2 = ?
P1V1 = P2V2
∴ V2 = `("P"_1"V"_1)/"P"_2`
= `(x xx 2500)/(7/2x)`
= `5000/7` cm3
