Question
Water decomposes to O2 and H2 under suitable conditions as represented by the equation below:
\[\ce{2H2O -> 2H2 + O2}\]
Taking the volume of H2 calculated in 5(b), what changes must be made in kelvin (absolute) temperature to return the volume to 2500 cm3 pressure remaining constant.
Solution
V1 = `5000/7`cm3
V2 = 2500 cm3
∴ T2 = `"V"_2/"V"_1 xx "T"`
= `(2500 xx 7)/50`T1
= 3.5 T1
∴ T2 is increased to 3.5 times.
