kinetically stable?

What does that mean

Basically the activation energy (the hump part of the graph) is high enough so that under normal conditions the reaction won't proceed.

This just means the reaction energy barrier is very high and but deltaG is negative

The conditions of the reaction will not favor the occurrence of the reaction, even if the reaction is spontaneous thermodynamically.

The energy barrier (the hump) is really large so it would take a lot of energy to do the reaction so it's most likely to stay as the reactant.

Means that it's stable enough to stay in reactant form- basically has a high energy barrier but still a negative G value.

I believe this means that the reaction's delta G is negative so it is technically spontaneous, but the reaction won't normally proceed because it has such a high activation energy.

It is thermodynamically spontaneous because delta G is negative, but it won't proceed normally because it has such a high activation energy.

To be stable, the reaction will have a negative deltaG value, so it is technically spontaneous. Although, there is a very large activation energy which prevents it from proceeding. Thus, it is kinetically trapped in reactant form.

This means the the activation energy, the hump in the reaction profile, is very high.

High Ea means that it takes a great deal of energy to start rxn so it is stable at standard conditions
