The Henry's law constant for N2 in water at 37 °C is 8.2 × 10-7 M/mm Hg. What is the equilibrium concentration of N2 in water when the partial pressure of N2 is 605 mm Hg
The linear molecule FeH2 has been observed in the gas phase. Assume that the iron atom can potentially use s, p, and d orbitals to interact with the hydrogens. If the z axis is collinear with the molecular axis
Use the steady state approximation, with O treated as the intermediate, to find an expression for the rate of decomposition of O3, i.e. -d(O3)/dt. (Note, do not set d(O3)/dt equal to zero). When step 2 is slow, the rate of decomposition of ozon..
