Unit 9- energy changes and reversible reaction Flashcards
1
Q
What is an exothermic reaction
A
The reaction that gives out energy
2
Q
What is an endothermic reaction
A
The reaction that takes in energy
3
Q
In the energy diagram if the reactant is placed lower than the product then is the reaction exothermic or endothermic
A
endothermic
4
Q
If the energy used to break bond is lower than the energy formed when making bond, the reaction is______
A
exothermic
5
Q
how to calculate energy changes
A
energy in - energy out
6
Q
If the overall energy change is negative then is the reaction exothermic or endothermic
A
exothermic
7
Q
what is an equilibrium
A
forward and backward reactions take place at the same rate. no overall change.
the amount of reactants and products remain steady
