Science has a lot of uses. It can uncover laws of nature, cure diseseases, make bombs, and help bridges to stand up. Indeed science is so good at what it does that there’s always a temptation(诱惑) to drag it into problems where it may not be helpful. David Brooks, author of The Social Animal: The Hidden Sources of Love, Character,and Achievement, appears to be the latest in a long line of writers who have failed to resist the temptation. Brooks gained fame for several books. His latest book The Social Animal, however, is more ambitious and serious than his earlier books. It is an 工业上利用CO与H2反应合成优质燃料甲醇。（1）已知燃烧6.4g甲醇放出145.16kJ热量，请写出表示甲醇燃烧热的热化学方程式：_______。（2）甲醇燃料电池具有能量密度大，对环境污染小等优点，有一种甲醇碱性燃料电池装置如图所示:①甲醇应由______(选填“a”或“b”)极通入，其电极反应式为___________；②当电路中通过1.2mol电子时，a极室n(OH-）减少____________mol；（3）已知：CO(g)＋2H2(g) CH3OH(g)　ΔH＝－129.0 kJ·mol－1，在一恒容密闭容器中，按照a mol CO和2a mol H2投料，测得CO在不同温度下的平衡转化率与压强关系如图所示，则下列说法正确的是____。a.温度：T1＞T2＞T3b．平均摩尔质量：M(a)＞M(c)、M(b)＞M(d)c．正反应速率：v(a)＜v(c)、v(b)＞v(d)d．平衡常数：K(a)＜K(c)、K(b)＝K(d)
