Answer

Transcription of this question: Consider the following Hess’s law cycle:CH2=CH2 (g) + H2 (g)+ 02 (g)step 2Step 1CH3CH3 (g)+ 02 (g)step 3(a)(b)(c)2C02 (g) + 31420 (l)Identify the type of reaction in step 1.Calculate the standard enthalpy change, AHO, of step 2 using section 13 of thedata booklet.Determine the standard enthalpy change, AHe, of step 1.(d) Suggest one reason why the calculated value of AHO using Hess’s Law in part (c) canbe considered accurate and one reason why it can be considered approximate.Accurate:Approximate:[2]
