Phosphorus and bromine react to form phosphorus tribromide, like this: P4(g) + 6Br2(g) 4PBr3(g) Also, a chemist finds that at a certain temperature the equilibrium mixture of phosphorus, bromine, and phosphorus tribromide has the following composition:
| compound | pressure at equilibrium |
|---|---|
| P4 | 50.1atm |
| Br2 | 19.6atm |
| PBr3 | 61.5atm |
Calculate the value of the equilibrium constant Kp for this reaction. Round your answer to 2 significant digits.
