Like heavy water (D₂O), so-called “semi-heavy water”(HDO) undergoes H/D exchange. The scenes below depict aninitial mixture of HDO and H₂ reaching equlibrium.(a) Write the balanced equation for the reaction. (b) Is the valueof Kgreater or less than 1? (c) If each molecule depicted repre-sents 0.10 M, calculate K.
The equilibrium constant for the reaction 2CrO42+2H+Cr2O72+H2O is 4.2 1014. The molar absorptivities for the two principal species in a solution of K2 Cr2 O2 are Four solutions were preparedby dissolving 4.00 10-4, 3.00 10-4, 2.00 10-4,and 1.00 10-4 moles of K2 Cr2 O7 in water and diluting to 1.00 L with a pH 5.60 buffer. Derive theoretical absorbance values (1.00-cm cells) for each solution and plot the data for (a) 345 nm, (b) 370 nm, and (c) 400 nm.
