Which diagram correctly represents the Boltzmann distribution of molecular energies at two temperatures T₁ and T₂, where T₁ = 300K and T₂ = 310K?

This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.

A[Diagram A showing Boltzmann distribution curve with T1 peak higher and to the left of T2 peak]
B[Diagram B showing Boltzmann distribution curve with T2 peak lower and to the right of T1 peak]
C[Diagram C showing Boltzmann distribution curve with T2 peak higher and to the left of T1 peak]
D[Diagram D showing Boltzmann distribution curve with T1 peak lower and to the right of T2 peak]

✓ Correct answer

B: [Diagram B showing Boltzmann distribution curve with T2 peak lower and to the right of T1 peak]
