Energy transfer in reactions Flashcards
Define ectothermic reaction?
An exothermic reaction is one where it gives out energy usually as heat and is shown in temperature
Combustion is a what kind of reaction?
Ectothermic reaction
Define endothermic reaction?
Endothermic reaction is one that takes in energy usually in the form of heat and is shown by fall in temperature
Adding acid to alkali is what kind of reaction?
Exothermic
Dissolving ammonium nitrate in water is a what kind of reaction ?
Endothermic
What happened during chemical reactions ?
Bonds are broken and new bonds are formed
What must be supplied to break existing bonds?
Energy
So what reaction is breaking a bond?
Endothermic
Is energy released of supplied when bonds are formed?
Released
What kind of reaction is this?
Exothermic
Is the energy used to break bonds greater or less than used to form?
Greater
