Question
Explain how increasing the temperature of a reaction typically affects the rate of reaction.
Answer
Increasingthe temperature usually increases the rate of reaction because it raises the energy of the particles. This leads to more frequent and more energeticcollisions between reactant particles, resultingin a higher likelihood of successful reactions.
Explanation
This question tests the understandingof the relationship between temperature and reaction rate, specifically how temperature influences particle energy and collision frequency. The answer demonstrates knowledge of collision theory.
Common mistake
Temperature effect misinterpreted
Students often think that increasing temperature always increases the rate of reaction, even for reactions that are endothermic or have a temperature-dependent equilibrium shift.
Explain that while higher temperature generally increases reaction rate by providing more kinetic energy and higher collision frequency, it can also shift equilibria or favour reverse reactions in some cases. Clarify that the temperature dependence of the rate is described by the Arrhenius equation and that the effect is not universal for all reactions.
