H2(g) + I2(g) 2 HI(g)
The forward reaction above is exothermic. At equilibrium, what happens if I2 is removed from the reaction mixture at constant temperature and volume?
The reaction absorbs energy.
The reaction releases energy.
[H2] increases.
[H2] decreases.
[H2] remains constant.
[HI] increases.
[HI] decreases.
[HI] remains constant.

i tried releases energy, H2 decreases, and HI increases.

    You didn't place an arrow. If the reaction is
    H2 + I2 ==> 2HI + heat and you remove I2, the reaction will shift to the left. That means,
    a. (H2) increases.
    b. (I2) decreases.
    c. (HI) decreases.
    d. heat is absorbed.
