To solve the problem, we need to determine how the rate of a reaction changes with an increase in temperature. The problem states that the rate of reaction doubles (increases by two times) for every 10°C rise in temperature. We are asked to find the new rate of reaction when the tempe...
• The frequency of collision increases and the fraction of particles possessing energy equal or greater than the activation energyincreases. • This results in an increase in the frequency of effective collisions between time. • Hence, rate of reaction increases. 当我们想答案时, 只需要想 fr...
