Question

2NO(g) + O2(g) → 2NO2(g) + 112 kJ
what do you do to increase the reaction rate?
decrease in pressure or increase in concentration of NO? HELP!

Answer 1

add more NO so that the equation will equilibrate by producing more NO2

Answer 2

NOTE: Changing pressure or concentration of any of the reagents will NOT change the rate. It will change the point of equilibrium but it will not change the rate. Increasing concn of NO or O2 and decreasing pressure of the system will force the equilibrium to the right.

Answer 3

You will need to add a catalyst.

'nic' is not correct as changing the P or concentrations will only change the position of the equilibrium.

Increasing the temperature will bring the reaction to equilibrium more quickly, but will decrease the equilibrium yield as it is an exothermic reaction.
