Select all of the following that are required for a chemical reaction to occur according to the collision model: molecules must collide molecular collisions must be properly oriented to allow new bonds to form to create products molecular collisions must meet or exceed a minimal energy threshold (energy of activation) collisions of molecules of the same chemical species will not yield a chemical reaction

Which of these are factors that impact rate of reaction? temperature reactant concentration presence of a catalyst O reactant particle size

A bimolecular reaction can involve a single reactant

Which of the following will lower the activation energy for a reaction?   Group of answer choices raising the temperature of the reaction. increasing the concentrations of reactants. increasing the surface area of the reactants. adding a suitable catalyst.
