The rate constant for electron transfer between V 2+ (aq) and V 3+ (aq) is observed to depend on [H+]: k = a + b/[H+], where a and b are constants. Propose a mechanism and express a and b in terms of the rate constants in your mechanism.
If carbon dioxide gas is collected over water at 25 °C and 775 torr, what is the partial pressure of the CO2? The vapor pressure of water at 25 °C is 23.8 torr.
A single strand of natural silk may be as long as 4.03 x 10^3 m. Convert this length into miles.
The freezing-point depression measurement of benzoic acid in acetone yields a molar mass of 122 g; the same measurement in benzene gives a value of 242 g
Select all of the correct statements about reaction quotients and equilibrium constants from the choices below. A reaction quotient equals the equilibrium constant at equilibrium. In a reacting mixture K is the ratio of product to reactant concent..
Based on their activation energies and energy changes and assuming that all collision factors are the same, which of the following reactions would be fastest and which would be slowest?
An aqueous solution is 36.0 % by mass potassium bromide, KBr, and has a density of 1.33 g/mL. determine the mole fraction of potassium bromide in the solution?

If a 20.0 °C drop in temperature causes a fortyfold decrease in reaction rate for a certain reaction, what is the activation energy of the reaction
Using information in Appendices B and C, calculate the minimum number of grams of C3H8(g) that must be combusted to provide the energy necessary to convert 3.25 kg of H2O from its solid form at -11.0°C to its liquid form at 70.0°C.
Clearly indicate coordinate system used in finding the answer. Basically trying to work up to building the molecular orbital diagram. I am stuck in the step where you determine the transformation sequences of each symmetry subset.
