What does the 2 represent on the energy diagram?

B) Change in energy between products and reactions, ΔH

A potential energy diagram for a chemical reaction is given below. Each interval on the potential energy axis represents 500. kilojoules of potential energy. What can be concluded from the diagram?

B) The reaction is endothermic, and the heat of reaction is +1000 kJ.

A) The reaction is endothermic, and the heat of reaction is -500 kJ.

C) The reaction is exothermic, and the heat of reaction is -500 kJ.

D) The reaction is exothermic, and the heat of reaction is +1000 kJ.

A model for a reaction is on the left; notice the coefficients. Based on this information, which statement is best supported by the model?

A) This is endothermic because the reactants have more energy than the products.

B) The total bond energies of the product molecules is equal to the total bond energies of the reactant molecules because the number and types of atoms are equal.

C) Energy is transferred to the surroundings when H2O2 decomposes because there are more bonds in the reactant molecules than the product molecules.

D) The average O=O bond energy is higher than the average O-O bond energy because more energy is released when a O=O bond forms than the energy absorbed when O-O bonds break.

Endothermic reactions tend to _________________.

Feel cold as they absorb energy.

Feel hot as they absorb energy.

Feel hot as they release energy.

Feel cold as they release energy.

What does the 1 represent on the energy diagram?

B) Change in energy between products and reactions, ΔH
