1
New cards
nature tends towards
stability
2
New cards
spontaneus
reactants are at a higher energy than products; nature tends towards stability; it goes to products without any external energy
3
New cards
non-spontaneous
products are at a higher energy than reactants; external energy is required
4
New cards
thermodynamically stable
a reaction which has an overall positive energy change (non-spontaneous, endothermic)
5
New cards
exothermic
\-∆H, spontaneous, unstable (before)
6
New cards
endothermic
\+∆H, non-spontaneous, stable (before)
7
New cards
kinetically stable
a reaction that proceeds so slowly that no change is detectable
8
New cards
stoichimetric reactions
go to completion, more are not stoichimetric, more are reversable (A + B ⇌ B + A)
9
New cards
dynamic equlibrium
when the rate at which the products are being formed is equal to the rate at which the products decompose
