The equilibrium constant (Keq) for the hydrolysis of ATP to ADP + Pi is 2x10(e5)M. The concentrations of reactants in cells are: [ATP]=5mM, [ADP]=0.5mM and [Pi]=5mM. Is the reaction at equilibrium in living cells?

This is a characteristic of the elements in the periodic table that shows a pattern. it may increase or decrease across or down the table.

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.
