It's pretty easy but I am just having trouble understanding it right now

The Kc is 2.33 at 110 Degrees Celsius

2NO <--> 1N₂ + 1O₂


What is the Kc value if the equation is reversed at same temperature?

What would the equilibrium quotient look like?
What would it look like if the reaction were reversed?

What does that represent mathematically?

well. If you think about Kc its product conc's over reactant conc's, and its a set value for a given temp.
Therefore if you want the reverse reaction you would turn the fraction upside down, so say if it was numerically 4/2 it would become 2/4 as the new value.
Hope that helps, my numbers are very basic but the principle remains.
