the mechanism for the reaction 2No +O2----> 2NO2. is believed to involve the following steps: 1- 2NO<----> N2O2 fast (k1,K^-1)2- N2O2 +O2---> 2NO2 slow
1- derive the rate equation using the steady state approximation for any intermediates.
2- experimentally the rate law is determined to be third order. under what conditions (if any) does your derived rate law agree with the experimental rate law?
3- describe two experiments and the results that would allow you to test the mechanism.
Spectroscopists have observed He+ in the outerspace. This ion is a one-electron species lik ea neutral hydrogenatom. Calculate the energy emitted for the transition from the n =5 to the n = 3 state in this ion using the equation:
The heat of vaporization of a liquid is the energy required to vaporize 1.00 mol of a liquid at its boiling point. In one experiment, 60.0 g of liquid nitrogen (boiling pt = -196C) is poured into a Styrofoam cup containing 200.0 g of water at 55.3..
calculate the change in internal energy for a system that is giving of 25.0 kJ of heat and is changing from 12.00 L to 6.00L in volume at 1.50 atm pressure.
Malonic acid is a diprotic acid used in the production of pharmaceuticals. A 0.6561 g sample of a m ixture of malonic acid (C3H4O4) and NaCl was titrated to the equivalence point with NaOH. The titration required 54.94 mL of 0.1009 M NaOH. Malonic..
An increase in which of the following will occur if the reaction temperature is increased? I. Energy of activation II. Collision frequency III. Fraction of collisions with sufficient energy
derive the rate equation in terms of [NO] and [O2] as well as k ( Assume N2O2 to be in a steady state )
Add the angular wave function for a 2s electron of Carbon to that of a 2py electron of the same carbon atom. Subtract one from the other. In what direction do the functions point? What orbitals are "left" unused on the C atom?
A 12.4 g sample of CaCl2 is dissolved in 112 g of water, with both substances at 25.0°C. Calculate the final temperature of the solution assuming no heat lost to the surroundings and assuming the solution has a specific heat capacity of 4.18 J/°C·..
Find the average value of the electron-nucleus seperationin a hydrogen like atom in the 2pz (ml=0) state.
a 1.0cm3 sample of lead and a 1.0cm3 of glass. I drop each in a separate beaker of water. How do the volumes of water that are displaced by the samples compare?
When 2 mole of A is reacted with 2 moles of B, 3 moles of C are formed. When 1 mole of A is reacted with 3 moles of B, 3 moles of C are again formed. Based on this, what is the balanced reaction?
