Based on the enthalpy diagram for exothermic reactions represented in the source text, what is the relative energetic relationship between the total enthalpy of reactants (\( H_r \)) and products (\( H_p \))?

Question diagram
  1. A
    H_r < H_p
  2. B
    \( H_r = H_p \)
  3. C
    \( H_r > H_p \)
  4. D
    \( H_r + H_p = 0 \)
View Answer & Solution

Correct answer · Option C

\( H_r > H_p \)

Explanation

In an exothermic reaction, heat is released, meaning the enthalpy of products is lower than that of reactants (\( H_r > H_p \)).
