Question

What is the difference between a spontaneous and a non spontaneous reaction?

Answer 1

from my previous knowledge i remember that non spontaneous reactions does not react under normal conditions, it need different variables to cause a reaction to occur such as temperature (i.e heating)

Answer 2

If a reaction is spontaneous that means the reaction will go as written. It doesn't say anything how fast it will go or how long it will take but the reaction will produce more products and the reactants will be used. Non-spontaneous means that the reaction, as written, will not go but it will go in the reverse direction.
