Consider the following equilibrium:

2so2(g) + o2(g) 2so3(g)

which of the following is a correct equilibrium expression?

a.
`"k"_("eq") = (["so"_3])/(["so"_2]["o"_2])`

b.
`"k"_("eq") = (["so"_3]^2)/(["so"_2]^2["o"_2])`
c.
`"k"_("eq") =(["so"_2]["o"_2])/(["so"_3])`

d.
`"k"_("eq") =(["so"_2]^2["o"_2])/(["so"_3]^2)`

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.

Idon't really understand this can you me and show your work.☺☺[ chemistry b] subject [ electron transfer in lonic bonds]grade( 12)
