Breaking bonds is hydrolysis. is dehydration synthesis. stores energy. is endergonic.

Which statements are true regarding reaction rates'[Select all that apply.] Larger activation energies are associated with faster reaction rates. Higher reactant concentrations are associated with faster reaction rates. Reducing the activation energy for a reaction increases its reaction rate. Reaction rates depend on how likely molecules are to collide in the correct orientation to react. Reactions that give off heat occur rapidly. Reactions that absorb heat occur rapidly. Large changes in enthalpy are associated with fast reaction rates. At high temperatures molecules are more likely to collide with enough energy to initiate a reaction. Two molecules must collide with one another to react.
