(c)Explain, in terms of particles, what happens to the rate of this reaction when the temperature is increased.[3] 相关知识点: 试题来源: 解析 (particles) have more energy OR (particles) move faster more collisions per second OR greater collision rate more (of the) particles OR collision ...
When particles have energy equal to or greater than the activation energy, they can collide successfully and react. Therefore, heating the reaction mixture increases the number of effective collisions between reactant particles, thus increasing the rate of the forward reaction. 加热反应混合物会增加...
What Affects the Rate of Reaction?
What are the units for rate of a reaction? Rate of a Reaction: Rate of a reaction is defined as the ratio between the change in concentration of reactants (or products) and the change in time. It determines how fast or slow the reactants are reacted to form products. Therefore, rate...
Temperature rises and the equilibrium constant decreases in case of what kind of a reaction? Does the equilibrium constant change as the temperature changes? If so, explain why the equilibrium constant changes? If the reaction equation is reversed, what happens to the value of...

The rate of a chemical reaction refers to the speed with which reactants are converted to products, the substances formed from the reaction. Collision theory explains that chemical reactions occur at different rates by proposing that in order for a reaction to proceed, there must be enough energ...
Calculate the overall order of a reaction which has the rate expresison. (a) Rate=k[A]12[B]32, (b) Rate=k[A]32[B]−1 View Solution What is the order of a reaction which has a rate expression, i.e. rate =k[A]3/2[B]−1?
heat up the tip of the match by striking it against the striker strip on the box, however, the temperature increases and with it the rate of the reaction until it burns with a hot flame. In general, the more you increase the temperature of an exothermic reaction, the faster it will go...
