Equilibrium
... The activation energy barrier for a catalyzed reaction is lower than that of a uncatalyzed reaction. With a lower activation energy barrier, more reactants have the energy to form products within a given time. Because a catalyst is not consumed during a reaction, it does not appear as a reactant or ...

(a) 1.81x1023 (b) 7.22x1024 (c) 6.02x1023 (d) 1.20x1025 (e) 4.70x1025 Hint: According to the chemical formula, one mole of CH4 contains 1 mole of C atoms and 4 moles of hydrogen atoms. Thus, the mole of H = 4 x {mass of CH4/molar mass of CH4}. ...
