    Q:

    		 Two biochemical mechanisms use the same reactants to produce the same products. The simplified, balanced reaction for both mechanisms is 2A + B → 2C. If one biochemical mechanism performs the reaction in 2 steps but the other mechanism performs it in 4 steps, how does the net enthalpy change of the reaction differ between the two biochemical mechanisms?
    		 

    A

    		 The enthalpy change for 4 steps is double the enthalpy change for 2 steps

    B

    		 The enthalpy change for 4 steps is 4 times more than the enthalpy change for 2 steps

    C

    		 The enthalpy change for 4 steps is half the enthalpy change for 2 steps

    D

    		 The enthalpy change for 4 steps is the same as the enthalpy change for 2 steps
