Which statement about spontaneity and reactions rates is true? Both temperature and pressure impact the rate of reaction and spontaneity. All spontaneous reactions are exothermic and have high reaction rates. All spontaneous reactions are fast and have fast reaction rates. The addition of a catalyst affects both the spontaneity and the rate of a reaction.
