Reactionrates
« on: November 02, 2008, 06:19:37 AM »
Hello! I have two questions that I could not find the answer to in my book.

1) Is the reaction rate of reactions proportional to the energy released?

2) Do you increase the rate of an endothermic reaction by increasing the temperature?

Reflection: 1) I would think that the reaction rate is proportional to the energy released in endothermic reactions because the reactants go from high to low energy products?.. But how does this work in endothermic reactions where energy is absorbed?

2) Isnt it so that you increase the rate of all reactions, endothermic or exothermic, by increasing the temperature?

Cheers!

the reaction rate depends on the energy of the transition state and not on the energy of reactants and products

so your answer to 2 is correct
