Phosphorus tribromide decomposes to form phosphorus and bromine, like this: 4pbr3 (g) → p4 (g) + 6br2 (g) write the pressure equilibrium constant expression for this reaction

Step I of the proposed mechanism involves the collision between NO2 and F2 molecules. This step is slow even though such collisions occur very frequently in a mixture of NO2 (g) and F2 (g).
