Interpretation:
If an endothermic reaction at equilibrium has an activation energy of 40kJ. The activation energy of the reverse reaction should be determined if the energy of reaction is 30 kJ.
Concept Introduction:
Endothermic reaction is the process where the energy of products is higher than that of the reactants. In simpler words,an endothermic reaction takes the energy from the surroundings.
The reverse of an endothermic reaction is called an exothermic reaction which gives off energy to the surroundings. In this reaction, the energy of reactants is higher than that of the products.
At equilibrium, the energy released is equal to the energy absorbed.

- SH 0arrow_forward2. Please consider the two all 'cis' isomers of trimethylcyclohexane drawn below. Draw the two chair conformers of each stereoisomer below (1 and 2) and calculate their torsional interaction energies in order to identify the lower energy conformer for each stereoisomer. Based on your calculations, state which of the two stereoisomers 1 and 2 is less stable and which is more stable. [1,3-diaxial CH3 CH3 = 3.7kcal/mol; 1,3-diaxial CH3 H = 0.88kcal/mol; cis-1,2 (axial:equatorial) CH3 CH3 = 0.88kcal/mol; trans-1,2-diequatorial CH3 CH3 = 0.88kcal/mol) all-cis-1,2,3- 1 all-cis-1,2,4- 2arrow_forwardNonearrow_forward
