Hydrogen and oxygen release enormous amounts of energy when they react. Yet, hydrogen and oxygen can be mixed together in a balloon and nothing will happen. Why? Competitive inhibitors are blocking the reaction from occurring in the active site The energy of activation to form the transition-state complex is too high to allow the reaction to occur without assistance All of these There must be contaminating elements in the balloon that prohibit the reaction from occurring TRUE ANSWER : ? YOUR ANSWER : ?
