1.Oon mole of a liquid is vaporized at its boiling point , 65 Cand 1.00atm.
deltaHvap for the liquid is 43.8 kj/mol at 65 C
(a)Calculate w.(in unit of J)
(b)Calculate deltaE(in unit of kj)
2.thw oxidation of Cr3+ to CrO42- can be accomplished using Ce4+ in a
buffered solution.the following data were obtained:
Initial rate [Ce4+] [Ce3+] [Cr3+]
1 2x10-3 1x10-2 3x10-2
2 4x10-3 2x10-2 3x10-2
3 4x10-3 1x10-2 3x10-2
4 8x10-3 2x10-2 6x10-2
