A. Problem Solving. Show all computations and round off final answers to two decimal places.
a. 10.0 moles of N2O were placed in a 2.00-L container at a given temperature where it decomposes according to:
N2O(g) ------------> N2(g) + O2(g)
At eq., 2.20 moles of N2O remain. Calculate the value of Kc for the reaction.
b. The equation for the following reaction and the value of Keq are given at a certain temperature.
An equilibrium mixture in a 1.00-L container contains 0.25 mol of PCl5 and 0.16 mol of PCl3. What equilibrium concentration of Cl2 must be present?
PCl3(g) + Cl2(g) ----------------> PCl5(g)
Keq = 1.9
B. Given the follwing reaction, predict which direction is favored by the system in each condition.
(forward or backward reaction?)
NO(g) + O2(g) -----------> NO2g + 28.1 kcal
- Increase in Pressure
