Chemical Kinetics - Show that only the reactants of the slow step of a reaction are found in the rate law of the reaction.
Consider the following reaction: NO2 + CO → NO + CO2
A suggested mechanism for the above reaction is given below:
NO2 + NO2 → NO3 + NO ------------ (step-1)
NO3 + CO → NO2 + CO2 ------------ (step-2)
If the rate law is known to be k[NO2]2, a) which of the two steps is slower? b) which substance (if any) is probably an unstable intermediate?
Calculate DeltaG °rxn. c) In which direction is the reaction, as written, spontaneous at 25 °C and standard pressure?
What is the pH of the solution created by combining 8.00 mL of the 0.10 M base with 8.00 mL of the 0.10 M acid?
Calculate the percent relative error for the three solutions if perfect technique is used. Report the two new molarities. (The error in a 10-mL transfer pipet is 0.02, and the error in the 200-mL volumetric flask is 0.1)
Suppose you have a 250 mL glass bulb containing an unknown amount of PCl3 gas. If the bulb contains 1.5 atm of PCl3 at 25C
A sample of 1-naphthoic acid is contaminated with a small amount of sand and NaCl. Using active extraction (changing the polarity) and a gravity filtration to remove a component, describe how you would obtain pure naphthoic acid from this mixture.
Draw the molecular orbitals for the following molecules. Label the hybridization of all non-hydrogen atoms BF3, CH20, O3
