Question

Consider the reaction below:

2 CO(g) + O₂(g) ⇌ 2 CO₂(g)

If Kc is 2.24 × 10²² at 1273.0 °C, calculate Kp at the same temperature.

Answer 1

To calculate Kp at a given temperature, use the equation Kp = Kc(RT)^Δn, where R is the ideal gas constant, T is the temperature in Kelvin, and Δn is the change in the number of moles of gas. In this case, Δn is 0, so the value of Kp is equal to the given value of Kc.

Step-by-step explanation:

To calculate the value of Kp at the given temperature, we can use the equation Kp = Kc(RT)^Δn, where R is the ideal gas constant, T is the temperature in Kelvin, and Δn is the change in the number of moles of gas between the products and reactants.

In this case, the reaction is 2 CO(g) + O₂(g) ⇌ 2 CO₂(g), and there is no change in the number of moles of gas, so Δn = 0

Plugging in the values, we have Kp = 2.24 × 10²² × (1273.0 + 273)^0

= 2.24 × 10²².
