Please explain- thanks!

Background and question:

What fraction of the CCl4 is converted into C and Cl2 ? Express your answer using two significant figures. Part B What is the partial pressure of CCl4 at equilibrium? Express your answer using two significant figures. At 700K the equilibrium constant for the reaction CCl4(g)C(s)+2Cl2(g) is Kp=0.76. A flask is charged with 1.60atm of CCl4, which then reaches equilibrium at 700K. What is the partial pressure of Cl2 at equilibrium? Express your answer using two significant figures.
