13.D〖解析】由反应历程图可知,甲醇解离时向外界释放能量,A项正确;催化剂N/MoC在该历程中最大能垒为-0.95eV-(-1.68eV)=0.73eV,催化剂MoC在该历程中最大能垒为-1.60eV(-2.90eV)=1.30eV,故Ni/MoC催化活性更高,B项正确;经历TS2的历程中能垒最大,为决速步骤,方程式为CH3O H=CH2O 2H或CH3O=CH2O H,C项正确;该历程的最后没有生成H2和CO2,故无法判断CH3OH(g) H2O(g)=CO2(g) 3H2(g)是否放热,也无法判断升高温度,反应CH3OH(g) H2O(g)=CO2(g) 3H2(g)的平衡常数的变化,D项错误。

第二节this time, Lewis was so distracted by the UFO.That's when the object entered the last cloud. From thereit was nothing but open sky. "When it appeared, my lifechanged, "Lewis says. "There against the richness of theblue sky was a silvery shape that seemed to have arms andlegs! It was so beautiful to look at. At the same time, ithad the appearance of metal. It looked like some kind ofship with a strange design. The best way I could describe itis that it looked like a silver tool in the design of thestickman children draw. It was huge, moving fasst anmade no noise.As it sailed overhead, some of the arms and legsould move up and down, giving the impression of beingalive!"He says. "It made a couple of rolls, reflecting thesun in every direction just beautiful! Slowly it landed onthe land. I imagined extraterrestrials would come out, butthat didn't happen. Then it began to rise and move fartherand farther away. As it started to fade away from myview, I found myself short of breath and with tearsrunning down my cheeks. It had that much of an effect onme. I began thinking maybe that's what an angel lookslike
