1. What is the reverse reaction of s of water?

2. Given that at 800k the concentrations are as follows: N2=3.0 × 10–3M, O2 = 4.2 × 10–3M and NO = 2.8 × 10–3M, what is the equilibrium constant for the reaction N2(g) + O2(g) \(\rightleftharpoons \) 2NO(g)?

3. Which of the following factors do you think will not affect the state of the equilibrium?

4. Equilibrium constant depends on the temperature.

5. ΔS(universe) > 0 can also be written as _________

6. Write pressure in terms of concentration and temperature.

7. If we use activities in place of molar concentration in an equilibrium constant expression then what is the dimension of k?

8. If KC of a reaction N2(g) + O2(g) \(\rightleftharpoons\) 2NO(g) is 2 x 10-3, then what is the KP?

9. What will happen if KC > 10-3 in a chemical reaction?

10. Consider the equation 2 H2 + O2 → 2 H2O, what does the 2 in the coefficient of H2O molecule represent?
