question 25

Multiple Choice

• B) Increasing the temperature will decrease reaction rate because,if the particles are moving faster,there will be fewer collisions.
• C) Both decreasing the reactant concentration and increasing the temperature will decrease reaction rate.
• D) Neither decreasing the reactant concentration nor increasing the temperature will decrease reaction rate.
