What are the three components of the Reactivity Triangle?

• A. Oxidizing Agent, Activation Energy, Reducing Agent
• B. Catalyst, Inhibitor, Solvent
• C. Pressure, Temperature, Humidity
• D. Electrode Potential, pH, Viscosity

Answer: (A)

Reactive behavior in this framework is defined by two chemical partners and the energy barrier between them. The oxidizing agent accepts electrons, the reducing agent donates electrons, and the activation energy is the amount of energy required to start the reaction. These three elements together determine whether a reaction can occur and how readily it proceeds, so they form the Reactivity Triangle. Factors like catalysts, inhibitors, and solvents can change how fast a reaction goes but aren’t the fundamental components that define reactivity. Environmental conditions such as pressure, temperature, and humidity affect rate but aren’t part of the core triad, and properties like electrode potential, pH, and viscosity describe specific reaction contexts rather than the universal reactive interaction.
