The gas phase reaction between nitrogen gas and oxygen gas to give NO gas is an endothermic process since 180.8 kJ of heat energy is absorbed when 1 mol of nitrogen reacts with 1 mol of oxygen. In which direction will the equilibrium be shifted if the temperature is increased?

will have no effect
shifts equilibrium to the left
shifts equilibrium to the right (is it this??)

thanks

I got it I just need help on this one...

The gas phase reaction between nitrogen gas and oxygen gas to give NO gas is an endothermic process since 180.8 kJ of heat energy is absorbed when 1 mol of nitrogen reacts with 1 mol of oxygen. In which direction will the equilibrium be shifted if the total pressure is decreased?

shifts equilibrium to the right
shifts equilibrium to the left
will have no effect

N2(g) + O2(g) + heat ==> 2NO(g)

The reaction tries to undo what we've done. Changing the pressure will shift the reaction to the side with the smaller number of moles. It appears to me that 2 moles are on the left and 2 moles on the right so..............

So no effect?

right.

When the temperature of a system at equilibrium is increased, the equilibrium will shift in the direction that absorbs heat, which is the endothermic direction. In this case, the forward reaction is the endothermic reaction that absorbs heat, so increasing the temperature will shift the equilibrium to the right. Therefore, the correct answer is "shifts equilibrium to the right."
