The rate of the reaction A + B ___> C + D
Was determined in the experiments at 225 OC. The results are:

Experiment [ A ](M) [B ](M) Initial Rate MS-1
1 0.263 0.826 1.44 x10^-5
2 0.263 0.413 1.44 x10^-5
3 0.526 0.413 5.76 x10 ^ -5

a. Determine the rate law for the reaction
b. Calculate the value of the rate constant at 225 oC
c. Calculate the rate constant of formation of D when [A]=[B]= 0.75M

One significant difference between an ionic bond, where electrons are taken from one atom and added to another atom, and a covalent or metallic bond, where electrons are shared is

1. suppose a reaction mixture, when diluted with water, afforded 300 ml of an aqueous solution of 30 g of the reaction product malononitrile [ch2(cn)2], which is to be isolated by extraction with ether. the solubility of malononitrile in ether at room temperature is 20.0 g/100 ml, and in water is 13.3 g/100 ml. what weight of malononitrile would be recovered by extraction with (a) three 100-ml portions of ether and (b) one 300-ml portion of ether? suggestion: for each extraction, let x equal the weight extracted into the ether layer. in part (a), the concentration in the ether layer is x/100 and in the water layer is (30 x)/300; the ratio of these quantities is equal to k 20/13.3.
