C(s) + H2O(g) + Heat <--> CO(g) + H2(g)

17. How would you adjust the temperature to increase the amount of product?

18. Does the removal of hydrogen gas as it is produced shift the reaction to the left or the right?

My last two questions on my homework that I just can't figure out. Please help, and thank you in advance!

17.
Based on the chemical equation, the reaction is endothermic. Increasing the temperature will favor the forward (left to right) reaction.
Or you may think of the heat as one of the reactants. If you increase heat, then the amount of products will also increase. Otherwise, it will decrease.

18.
Yes, it will favor the forward reaction, because as you remove the H2 gas, there would be no or little amount of H2 left to react with CO to yield C, H2O and heat.

Hope this helps~ :3
