Newton's first law of motion states that a. cceleration is calculated by dividing the force exerted on an object by the mass of the object b. an object will remain at rest or keep moving with a constant velocity unless a force acts on it c. when a force is applied on an object, there is an equal force applied by the object in the opposite direction d. when a force acts on an object, its acceleration is in the same direction as the force

How does a catalyst increase the speed of a reaction? a. the catalyst eliminates the activated complex stage, allowing products to form immediately. b. the catalyst lowers the energy level of the reactants, making it easier for them to react. c. the catalyst makes it easier for the activated complex to form, lowering the activation energy. d. the catalyst raises the energy level of the products, making the reaction finish sooner. reset next
