1. 1.25 moles of NOCl were placed in a 2.50 L reactionchamber at 427ºC. After equilibrium was reached, 1.10 moles of NOCl remained. Calculate the equilibriumconstant, Kc, for the reaction 2NOCl(g) ? 2NO(g) + Cl2(g).
2. Hydrogen iodide decomposes according to the equation2HI(g) ? H2(g) + I2(g), for which Kc = 0.0156 at 400ºC. 0.550 mol HI was injected into a 2.00 Lreaction vessel at 400ºC. Calculate the concentration of HI at equilibrium.
Draw a rough sketch of the energy profile for each of the following cases. a. E = +10 kJ/mol, Ea = 25 kJ/mol b. E = -10 kJ/mol, Ea = 50 kJ/mol c.
Starting with a sample of (R)-2,3-dimethylhexan-3-ol, provide the best synthesis of (R)-3-chloro-2,3-dimethylhexane
Calculate the equilibrium concentration of all the gases. This is the equation: 2NO(g)+2H2(g)=> N2(g)+2H2O(g). ( My instructor said that using the ICE table is a good method. if that helps in any way)
What volume of 0.0500 M NaOH must be added to remove the first acidic hydrogen from each aspartic acid molecule (i.e., to reach the first equivalence point)
The rule works particularly well for weakly interacting molecules, such as those of a noble gas, but not so well for water among other substances. Assuming the rule is exact, estimate the molar enthalpy of evaporation for Argon (in kJ/mol), whose ..

Show the bond angles which are at least slightly different that are shown by the H2CCBr2 molecule.
Calculate the % ionization in a 0.3458 M solution of o-iodobenzoic acid. The Ka of o-iodobenzoic acid = 1.7 x 10-3.
A solution is prepared by dissolving 17.6g Ammonium sulfate(NH_4)_2SO_4 (Molar Mass: 132.17g/mol) in enough water to make 121.0mL (0.121L) of stock solution. A 12.30mL (0.0123L) sample of this stock solution is added to 59.00mL of water. Calculate..
