Which of the following provide(s) a valid description relating collisions and reaction rate? Decreasing the reactant concentration will increase reaction rate because if there are fewer particles there is more room to collide. Increasing the temperature will decrease reaction rate because if the particles are moving faster there will be fewer collisions. both of the above neither of the above
