Explanation The reaction steps involved in the formation of hydrogen iodide are as follows. The fast step is reversible and represented as follows: I 2 ⇌ k − 1 k 1 2 I The rate of formation of the intermediate I can be expressed as follows: dI d t = 2 k 1 [ I 2 ] (1) The rate of deformation of I can be expressed as follows: − dI d t = k − 1 [ I ] 2 (2) The second step is also fast and represented as follows: I+H 2 ⇌ k − 2 k 2 H 2 I The rate of formation of H 2 I can be calculated as follows: d [ H 2 I ] d t = k 2 [ I ] [ H 2 ] (3) The rate of deformation of H 2 I can be calculated as follows: − d [ H 2 I ] d t = k − 2 [ H 2 I ] (4) The slow step is the rate-determining step and represented as follows: H 2 I+I → k 3 2HI The rate of formation of HI can be expressed as follows: 1 2 d [ HI ] d t = k 3 [ I ] [ H 2 ] (5) Steady-state approximation (SSA) is defined as the rate of formation is equal to the rate of deformation for any compound. Apply steady-state approximation and equate right-hand expression of equations (1) and (2) as follows: k − 1 [ I ] 2 = 2 k 1 [ I 2 ] or [ I ] = 2 k 1 k − 1 [ I 2 ] Apply steady-state approximation and equate right-hand expression of equations (3) and (4) as follows: k 2 [ I ] [ H 2 ] = k − 2 [ H 2 I ] or [ H 2 I ] = k 2 k − 2 [ I ] [ H 2 ] Substitute
