For the following reaction at equilibrium in a reaction vessel which change will cause the Br2 concentration to decrease?2NOBr(g) 2NO(g) Br2(g) ?Hºrxn= 30 kJ/molIncrease the temperature.Remove some NO.Add more NOBr.Compress the gas mixture into a smaller volume.Add a catalystThe answer is boldedI just don’t understand the theory
