New cards

when do chemical reactions occur?

chemical reactions can only occur when reacting particles collide with each other and with sufficient energy

2
New cards

what is activation energy (Ea)?

the minimum amount of energy that particles must have to react (to collide with each other)

So the greater the activation energy, the more energy needed to start the reaction

3
New cards

describe the reaction profile for an exothermic reaction.

  • as the products are at a lower energy than the reactants

  • difference in height = overall energy change in the reaction per mole

  • initial rise = activation energy

New cards

describe the reaction profile for an endothermic reaction.

  • products are at a higher energy than the reactants

  • difference in height = energy taken in per mole

<ul><li><p>products are at a higher energy than the reactants</p></li><li><p>difference in height = energy taken in per mole </p></li></ul>
