What is the activation energy of a reaction?A.The speed at which the molecules must be moving in order to reactB.The kinetic energy of the colliding moleculesC.The energy that is given off when a reaction happensD.The energy the molecules must have in order to reactSUBMITarrow_backPREVIOUS

The activation energy of a chemical reaction is the energy that:Group of answer choicesinitiates the reaction. activates the catalyst.is the difference in the energies of the starting materials and products.must be released from the mixture.must be removed from the mixture.

Activation energy of any chemical reaction can becalculated if one knows the value of(1) orientation of reactant molecules duringcollision.(2) rate constant at two different temperatures.(3) rate constant at standard

The magnitude of the energy of activation determines the _____ -- how fast the reaction occurs.

Activation energy can be described as __________.View Available Hint(s)for Part Aenergy needed to activate an enzymemetabolismenergy that must be invested to start a reactionenergy released by a chemical reaction

The energy of activation is the minimum amount of energy needed for a reaction to take place and is often called the _____ that must be crossed.
