What does the relationship ∆ r H = Σ(∆H(bonds broken)) - Σ(∆H(bonds formed)) represent?

Options

  1. AIt calculates the mean bond enthalpies of reactants and products.
  2. BIt determines the electrical conductivity of a substance.
  3. CIt predicts the enthalpy change of a reaction based on bond enthalpies.
  4. DIt measures the temperature change during a chemical reaction.

Correct answer

C. It predicts the enthalpy change of a reaction based on bond enthalpies.

Step-by-step solution

The relationship ∆ r H = Σ(∆H(bonds broken)) - Σ(∆H(bonds formed)) is used to predict the enthalpy change of a reaction based on bond enthalpies.
