Problem

The reaction below has an equilibrium constant Kp = 2.2 x 10 at 298 K.

2COF2(g)⇌CO2(g)+CF4(g)

Calculate Kp for the reaction below.

COF2(g) ⇌ 1/2CO2(g) + 1/2CF4(g)

Express your answer using two significant figures.

Solution

Use Hess's Law to find the Kp of the 2nd reaction

•Manipulate the 1st reaction to get 2nd reaction 

• Do corresponding changes to the Kp value of the 1st reaction = Kp value of the 2nd reaction
