Question

Solve the following problem. Your solution should follow the ICE strategy and your final answer should have the correct units and number of significant figures.

For the reaction H2 + I2 -><- 2 HI at equilibrium, the 5 L reaction vessel contains 2.0 mol of H2, 4 mol of I2, and 3 mol of HI. How many moles of H2 need to be added to increase the concentration of HI to 0.84 mol/L?

The biggest problem I'm running into is how to complete the ICE chart for the columns Change and Revised Equilibrium. I don't know where those numbers come from.

If there are multiple answers I will pick the one that is layed out the neatest.

Thanks!
