Consider the following equation: N2+O2 _ 2NO. The partial pressure (ln atm) of N2 under normal atmospheric pressure
Correct answer: B. 0.25
- A. 0.05
- B. 0.25
- C. 0.35
- D. 0.45
Explanation
Partial pressure = moles of substance/total moles * total pressure =moles of N2/total moles * total pressure =1/4 * 1 atm = 0.25

About Reversible Reactions
A reversible reaction proceeds in both forward and backward directions, so reactants and products continue changing until dynamic equilibrium is established. The topic covers the meaning of equilibrium, the equality of forward and reverse rates, and how concentration, pressure and temperature disturb equilibrium, which is separate from the rate at which equilibrium is reached.
