PLEASE HELP H2 + I2--> 2HI Consider this synthesis of hydrogen iodide as a reaction that has reached equilibrium. If the concentration of hydrogen gas and
iodine gas were decreased in this system, what is most likely to occur?
-The amount of hydrogen gas will increase.
-The amount of HI will decrease.
-The amount of Iodine gas will increase.
-All of the above are true.

Answer is in the photo. I couldn't attach it here, but uploaded it to a file hosting. link below! Good Luck!
