# Determine the position of an equilibrium process

For the exothermic reaction of nitrogen gas with iodine solid to produce nitrogen triodide gas. Write the balanced equation including heat and select the overall direction of shift in the reaction.

I have balanced the equation: $\ce{N2 (g) + 3 I2 (g) <=> 2 NI3}$ Is this equation correct?

I am confused on how to find the overall direction of shift. Should I use the Le Chatelier's principle? If so, then I think the overall shift is a "shift to the left"/reverse reaction. Am I correct?
