Question

What volume of hydrogen gas is produced when 0.685 mol of carbon monoxide reacts completely according to the following reaction at 0°C and 1 atm?

carbon monoxide ( g ) + water ( l ) carbon dioxide ( g ) + hydrogen ( g )

=_________ liters of hydrogen gas?

Answer 1

CO + H2O ----------------> CO2 + H2

1 mole Co                                   1 mole of H2

1 mole of CO react with H2O to gives 1 mole of H2

0.685 moles of CO react with H2O to gives 0.685 moles of H2

P = 1atm

T = 273K

PV = nRT

V = nRT/P

    = 0.685*0.0821*273/1   = 15.35L >>>>>answer

the volume of H2 is 15.35L
