Answer those blank. Show complete solutions. (c) Consider the equation for hydrogen consumption mµ2 in a fuel cell:P,(W)H, usage(kg/s) =1.05×10*V (V)Convert this equation to one where hydrogen usage is reported in mol/hr.Jason M. KeithStudent ViewSupplemental Material for Elementary Principles of Chemical ProcessesStrategyWe can use unit conversions to determine a new equation for the hydrogen consumptionrate.SolutionStart with the equation and the given units, writing the usage rate as a ratio of mass perunit time.Mass (kg)H, usage(kg/s) =Time (s)Then we have:2.02(g) (kg)Mass (kg) = Moles (mol)-Moles(mol) 1000(g)And we also have:60 (s)Time (s) = Minutes(min).= 60Minutes(min)Substituting into the left hand side of the formula for hydrogen usage, we have:Mass (kg)MolesMolesH¸ usage(kg/s) =Time (s)60MinutesMinutesInserting into the full formula for hydrogen usage, we have:P,(W)H, usage(mol/min) =V,(V)

Given, H2 usage (kg/s) = Mass (kg) / Time (s) Time (s) = Minutes (min) * 60 (s) / (min) = 60…

Mass (kg) H, usage(kg/s) = Time (s) Then we have: 2.02(g) (kg) Mass (kg) = Moles (mol)- Moles (mol) 1000(g) And we also have: 60 (s) Time (s) = Minutes(min). (min) 60Minutes Substituting into the left hand side of the formula for hydrogen usage, we have: Mass (kg) Moles Moles H, usage (kg/s) = Time (s) 60Minutes Minutes Inserting into the full formula for hydrogen usage, we have: P,(W) V,(V) H, usage(mol/min)

Mass (kg) H, usage(kg/s) = Time (s) Then we have: 2.02(g) (kg) Mass (kg) = Moles (mol)- Moles (mol) 1000(g) And we also have: 60 (s) Time (s) = Minutes(min). (min) 60Minutes Substituting into the left hand side of the formula for hydrogen usage, we have: Mass (kg) Moles Moles H, usage (kg/s) = Time (s) 60Minutes Minutes Inserting into the full formula for hydrogen usage, we have: P,(W) V,(V) H, usage(mol/min)
