31．(10分)CO和CO2都可以合成甲醇：CO+2H2→CH3OH；CO2+3H2→CH3OH+H2O，CO、CO2和H2可通过下列反应制备；①CH4+H2O(g)→CO+3H2；②CO+H2O(g)→CO2+H2；
反应①的产物合成甲醇时H2过量，反应②的产物合成甲醇时H2不足。为了充分利用原料，可将两个反应的产物混合使用。
(1)反应①和反应②的产物气体混合的最佳比例为 。
(2)以CH4、CO、H2O混合气体为原料气，在一定条件下充分反应，所得气体以合成甲醇，为使原子的利用率达到最高，则CH4、CO、H2O的最佳配比为 。
(3)若以100LCH4和H2O的混合气体为原料，制备CO、CO2和H2混合气体，当CH4和H2O均完全反应后，在相同条件上反应后的气体的体积为 (写范围)。
