KEY CONCEPT Life depends on chemical reactions. How does the Venus flytrap work?

Bonds break and form during chemical reactions. Chemical reactions change substances into different ones by breaking and forming chemical bonds. Reactants are changed during a chemical reaction. Products are made by a chemical reaction.

Phet simulation https://phet.colorado.edu/en/simulation/reactants-products-and-leftovers

Bond energy is the amount of energy that breaks a bond. Energy is added to break bonds. Energy is released when bonds form. A reaction is at equilibrium when reactants and products form at the same rate. CO2 + H2O H2CO3

Chemical reactions release or absorb energy. Activation energy is the amount of energy that needs to be absorbed to start a chemical reaction.

What do you call this reaction and what are the characteristics of it What do you call this reaction and what are the characteristics of it? Explain your answer using the graph Reactants have higher bond energies than products. Excess energy is released by the reaction.
