4-step explanation. Step 1: 'WHAT IS Ea? The minimum energy that colliding molecules need for a reaction to occur. Think of it as an energy hill molecules must climb over. Even exothermic reactions need this initial push (like striking a match).' Step 2: 'THE ARRHENIUS EQUATION: k = Ae^(-Ea/RT). k =
