Question 4

• hydrogen gas can be made industrially by reacting natural gas with steam
• CH₄ + H₂O → CO+3H₂
• calculate the atom economy of this reaction giving the answer to 2dp

Answer 4

• find the M_r of all the products 28+6=34
• M_r of desired characters 2x1= 2 2x3=6
• atom economy w total M_r of desired products/total M_r of all products x100
• 6/34x100=18%
