Chemical reactions: C. require collisions between reactants, therefore the reaction rate increases when the concentration of the reants is greater.

are written with the product on the left and the reactant on the right with an arrow to indicate the direction of the reaction. only break chemical bonds or form them but never in the same reaction. proceed spontaneously if the free energy of the product is greater than that of the reactant. proceed spontaneously through a low-energy transition staté to product.
