← ScienceWhich consequence results when the activation energy barrier exceeds available heat for cracking?
A)Greater yield smaller alkene molecules
B)Reduced end product total yield✓
C)Radical chain reactions rapidly accelerate
D)Isomerization reactions become thermodynamically favoured
💡 Explanation
Product yield decreases when activation energy for thermal decomposition of hydrocarbons exceeds available heat because many reactions will fail to initiate via the Arrhenius equation, therefore total product yield is reduced, rather than smaller molecular alkenes being favored.
