The equilibrium constant for the reaction, N2(g) + O2(g) ⇋ 2NO(g) is 4 × 10^-4 at 2000K. Find an answer to your question The reaction n2(g)+o2(g)⇌2no(g) contributes to air pollution 1. 11.no和co气体均为汽车尾气的成分,这两种气体在催化转换器中发生反应:2co(g)+2no(g)=n2(g)+2co2(g) h1.已知2no(g)+o2(g)═2no2(g) h2;co的燃烧热 h3;2no2(g)+4co(g)═n2(g)+4co2(g) h4;则下列关系式正确的是( ) a. h4= h1+ h3﹣ h2 b. h4= h1+2 h3﹣ h2 c. h4= h2+ h1+2 h3 d. h4=2( h2﹣ h1+2 h3). Notice that I have also changed the sign on the enthalpy from positive to negative. Please show me the way. N2(g) + O2(g) <-> 2NO(g) If more NO is added, bringing its concentration to 0.
