(b) The isomerisation of cis to trans butene is catalysed by iodine. cis-CH3CH=CHCH3 + 12 (cat) → trans-CH3CH=CHCH3 A mechanism for this reaction is provided below: 12 = 21* 1* + cis-CH3CH=CHCH3 CH3CHI K-1-*CHCH3 CH3CHI-*CHCH3 → trans-CH3CH=CHCH3 K₁/ K-1 K₂1 K-2 K3 Using this mechanism: (i) Write the rate law for the uncatalyzed reaction. (ii) Identify the reaction intermediates and give the chemical structures. (iii) Explain whether the Steady State Approximation can be applied to obtain the rate law from the proposed mechanism. (iv) Derive an expression for the rate law for the formation of trans-CH3CH=CHCH3.
