A reaction's ΔH is negative. Which energy diagram represents it?
A.Products lower than reactants
B.Products higher than reactants
C.Products level with reactants
D.No energy difference shown
Explanation
Core Concept
Negative ΔH means the system lost energy, so the products' line sits below the reactants'. The peak between them is still the activation barrier.
Correct Answer
AProducts lower than reactants
