Indicate the rate of change of all other species in the reaction in terms of the rate if change of O 2 is ∆[O 2 ]/∆t. 2 NO + O 2 2 NO 2 ∆[Ο 2 ] ∆τ = ∆[ΝΟ] 2∆τ = - ∆[ΝΟ 2 ] 2∆τ (4)2. How many grams of glycerin (C 3 H 8 O 3 ) must be added to 200 g of water to produce a solution that will boil at 110°C? (For H 2 O: K f = 1.86°C/m K b = 0.52°C/m) ∆T b = BP soln – BP solvent = 110 °C – 100°C = 10°C μ = ∆Τ β Κ β = 10 ο Χ 0.52 ο Χ/ μ = 19.2 μ # μολ Χ 3 Η 8 Ο 3 = 200 γ Η 2 Ο ξ 1 Κγ 1000 γ 19.2 μολ Χ 3 Η 8 Ο 3 1 Κγ Η 2 Ο = 3.84 μολ Χ 3 Η 8 Ο 3 # γ Χ 3 Η 8 Ο 3 = 3.84 μολ Χ 3 Η 8 Ο 3 ξ 92 γ Χ 3 Η 8 Ο 3 1 μολ Χ 3 Η 8 Ο 3 = 353 γ Χ 3 Η 8 Ο 3 (4) 3.
