Questions & Step-by-Step Solutions

What is the value of the equilibrium constant Kp for the reaction: N2(g) + 3H2(g) ⇌ 2NH3(g) at 25°C?
  • Step 1: Understand that Kp is the equilibrium constant for gas-phase reactions and is calculated using the partial pressures of the gases involved.
  • Step 2: Recognize that the reaction given is N2(g) + 3H2(g) ⇌ 2NH3(g).
  • Step 3: Identify that to calculate Kp, you need the partial pressures of N2, H2, and NH3 at equilibrium.
  • Step 4: Note that the value of Kp depends on the specific conditions of the reaction, such as temperature and concentrations.
  • Step 5: Realize that without knowing the initial concentrations or how far the reaction has gone, you cannot calculate Kp.
