Boltzmann Distribution Temperature Comparison

Steps:

• Observe the peak height: taller, narrower peak indicates lower temperature due to less kinetic energy spread.
• Compare curve widths: broader curve with lower peak signifies higher temperature and more high-energy particles.
• Verify total area: equal areas confirm same total particles at both temperatures.
• Assess shaded region: it represents fraction exceeding activation energy, but specify which temperature it applies to.

Why A is correct:

• Lower temperature (T1) produces a taller, narrower distribution curve, as per the Maxwell-Boltzmann equation where peak shifts left with decreasing T.

Why the others are wrong:

• B: Shaded area likely shows reactive particles at T1, not T2, based on typical diagram conventions.
• C: While fixed amount implies equal areas, the diagram may normalize differently, making totals appear unequal.

Final answer: A
