enegrtics Flashcards
Endothermic
Reactions in which heat energy is taken in from the surroundings.
Exothermic
Reactions in which heat energy is given out to the surroundings.
Activation energy
Minimum amount of energy required to result in a reaction (successful collision).
Calorimetry
Measuring the heat given out or taken in by a chemical reaction.
Enthalpy change
The amount of heat energy taken in or given out in a chemical reaction. (ΔH)
Molar enthalpy change
The change in enthalpy when 1 mole of a particular reactant reacts.
Fuel
A substance that when burned in oxygen releases heat energy
What is the activation energy? How does a catalyst affect this?
It is the minimal energy required for a reaction to take place. A catalyst provides another route for the reaction with a lower activation energy
