Nitrogen dioxide can be formed from nitrogen oxide and oxygen.


2 NO (g) + O2First order chemical reaction has an activation energy of 15.0 kilojoules per mole. The rate constant, K, is 1.5 x 10 to the negative third at 25 degrees Celsius what should the rate constant be at 45 degrees Celsius? (g) = 2 NO2 (g)


Add 1000 K, the equilibrium constant KC is 1.20


System of NO, O2 and NO2 is analyzed and the following concentrations are found: [O2]= 1.25 M; [NO]=2.25 M; [NO2]=3.25 M


A.) is the system at equilibrium with respect to the reaction above? Show your work


B.) if it is not at equilibrium will the concentration of NO2 increase or decrease as a system precedes to equilibrium. briefly explain your answer
