2. Given the reaction: N2(g) + 3H2 (g) = 2NH3 (g)
If Kc for this reaction is 4.5 x 10-4 at 400 K, what is the equilibrium constant KR
at the same temperature?
Consider the reaction:
CO(g) + 2 H,(8) = CH,OH(g)
A reaction mixture in a 5.19-L flask at a certain temperature con-
tains 26.9 g CO and 2.34 g H2. At equilibrium, the flask contains
8.65 g CH;OH. Calculate the equilibrium constant (K) for the
reaction at this temperature.
Consider the reaction 2 SO2(g) + O2(g) 2 SO3(g) at 1000 K. In a 1.00 L reaction vessel, 0.440 mol SO2, 0.220
mol O₂ and 0.440 mol SO3 are introduced simultaneously. If the Kç is 2.82 x 10², which of the statements
below is TRUE?
Q > Kc so the reaction will proceed in the reverse direction to attain equilibrium.
The reaction is at equilibrium since T is constant.
O Kp = Kc since T is constant.
O Q< Kc so the reaction will proceed forward and form more SO3 to attain equilibrium.

- Maple syrup sap is 3% sugar (sucrose) and 97% water bymass. Maple syrup is produced by heating the sap toevaporate a certain amount of the water. (a) Describe what happens to the composition and boilingpoint of the solution as evaporation takes place. (b) A rule of thumb among maple syrup producers is thatthe finished syrup should boil about 4 C higher than theoriginal sap being boiled. Explain the chemistry behindthis guideline. (c) If the finished product boils 4 C higher than the originalsap, calculate the concentration of sugar in the finalproduct. Assume that sugar is the only solute and theoperation is done at 1 atm pressure.arrow_forwardIn a solution with carbon tetrachloride as the solvent, the compound VCl4. undergoes dimerization: 2VCl4V2Cl8 When 6.6834 g VCl4. is dissolved in 100.0 g carbon tetrachloride, the freezing point is lowered by 5.97C.
