2)What is the osmotic pressure of a solution made by dissolving 65.0 g of glucose, C6H12O6, in enough water to form 200.0 mL of solution at 43.0 ∘C?
3)A certain reaction with an activation energy of 115 kJ/mol was run at 485 K and again at 505 K . What is the ratio of f at the higher temperature to f at the lower temperature? f505/f485=?
4)The gas-phase reaction of NO with F2 to form NOF and F has an activation energy of Ea = 6.30 kJ/mol and a frequency factor of A = 6.00×108M−1⋅s−1 . The reaction is believed to be bimolecular:
NO(g)+F2(g)→NOF(g)+F(g)
What is the rate constant at 657 ∘C ?
5)In the first 14.0 s of the reaction, 1.7×10−2 mol of O2 is produced in a reaction vessel with a volume of 0.360 L . What is the average rate of the reaction over this time interval?
rate=M. s-1
part b:Predict the rate of change in the concentration of N2O over this time interval. In other words, what is Δ[N2O]/Δt?
Δ[N2O]/Δt=M. s-1
6)Consider the following data showing the initial rate of a reaction (A→products) at several different concentrations of A.
[A](M) Initial Rate (M/s)
0.100 0.058
0.200 0.464
