c5.3 reversible reactions Flashcards
1
Q
dynamic equilibrium
A
when the forward and backward reactions still happen
2
Q
increasing pressure
A
the E.P moves in the direction of the fewest moles
3
Q
increase the concentration
A
the E.P moves away from that substance
4
Q
increase temperature
A
the E.P moves in the direction of the endothermic change
5
Q
negative change in energy
A
exothermic
6
Q
positive change in energy
A
endothermic
7
Q
how to choose a suitable pressure
A
high enough for a good rate of reaction
but
can be expensive and dangerous
8
Q
how to choose a suitable temperature
A
low temperatures means low rate of reaction
also high temperatures are dangerous
