It is highly hazardous, it is radioactive
Explanation:
This is because gas particles are free to move as they are not held in place by strong molecular forces while particles in a solid are
Kc= concentration of product divided by concentration of reactant
NO + NO2 ----> N2O3
Kc =(N2O3) / (No)(NO2)
Kc= ( 1.3 )/{ (3.9)(3.8) }
Kc=0.088 ( answer B)
