Interpretation Introduction
Interpretation:
The given
Concept introduction:
The heat released on combustion of a substance is called its heat of combustion. Combustion of hydrocarbons is exothermic and gives carbon dioxide and water as products.
Alkenes with more highly substituted double bonds are more stable than isomers with less substituted double bonds.
Branched alkenes are more stable than unbranched alkenes. The most stable alkene has the smallest heat of combustion.

- The reaction for obtaining NO2 from NO and O2 has the rate equation: v = k[NO]2[O2]. Indicate which of the following options is correct.(A). This rate equation is inconsistent with the reaction consisting of a single trimolecular step.(B). Since the overall order is 3, the reaction must necessarily have some trimolecular step in its mechanism.(C). A two-step mechanism: 1) NO + NO ⇄ N2O2 (fast); 2) N2O2 + O2 → NO2 + NO2 (slow).(D).
