Chemistry G - Exothermic and Endothermic reactions Flashcards
1
Q
Exothermic
A
Reacting chemicals transfer heat energy to the surroundings
2
Q
Explain bonds in terms of exothermic reactions
A
Energy released when new bonds formed is greater than energy absorbed when bonds break
3
Q
Endothermic
A
Reacting chemicals take in energy from the surroundings
4
Q
Explain bonds in terms of endothermic reactions
A
Energy released when new bonds form is lesser than energy absorbed to break bonds.
5
Q
Factors affecting rate of reaction
A
Catalysts
Pressure of gas
