The reaction: CH3CH2NO2+OH- --> H2O+CH3CHNO2- obeys the rate law d[A]/dt=-k[A][OH-], where A denotes CH3CH2NO2. It takes 0.5 min for one percent of the A to react at 25C, in the case of a solution 0.002M in A and 0.3M in NaOH. Calculate k. Calculate also how long it would take for half of A to react. **HINT: assume pseudo first order with k'=k[OH-], since [OH-] is in great excess.
The solvolysis of benzyl chloride proceeds via a carbocation intermediate and occurs more rapidly than the solvolysis of 2-chloro-norbornane and tertiary butyl chloride.
Assign absolute configurations to the chiral carbons n one of your Fischer projections. Indicate which of the compounds you have drawn would be optically active. Explain your reasoning.
Assume that the kinetic energy of a 1500kg car moving at 95 km/h can be converted entirely into heat. What amount of water could be heated from 20 C to 50 C by the car's energy?
Important information about Finding expressions for the partial molar volumes at T and P, The molar volume (cm^3 mol^-1) of a binary liquid mixture at T and P is given by: V = 120x1 + 70x2 + (15x1 + 8x2)x1x2 (a) Find expressions for the partial mo..
