10.D【解析】在0~10min内,△n(CO)2)=0.75mol△n(I2)=0.75moX3=2.25mol,故v(H:)=2.25 ol0.51.x1omin0.5mol·L.·min',A顶错误。容器容积恒定,混合气的总质量保持不变,故密度始终不变,B明错误,在15~18min时,n(CO:)增多(CH1O)跛小,说叨平衡向左移动,且二者的变化磧相说明反应不是战小n(CO2)或增加n(CH3OH),可能是升高温度或者减小压强:在15~18min内,△n(I2)=3M(CO2)=0.75mol,故v(l-)0.5L.×3min0.5moL.min“.連率大于0~10min,说明采川的是升高温度的方法,不是减小压强;若减少氢气的量,平衡向左移动,但连率减假,C项错误。在18mi时,反应重新达到早衡状态,n(CO:)=n(CI,(Il)=n(H, ()=0.5 mol Mn(I2)=3.5mo-1.5mo=2mol平衙时各物质的浓度cCO2)=cCO=c(H)=0.51.=1.0mol·L.',r(H2)≈2:0mol0.5L=4.0mol·L.·,故化学反应的平衡常数K,≈1×11,D项正确,1×4361
