In a 2.00L reaction vessel at 440C, hydrogen gas and iodine gas react to from hydrogen iodide gas. The equilibrium constant is 49.7. Determine the equilibrium concentrations for all the chemicals if 4.00 moles hydrogen gas and 1.99 moles iodine gas are combined, and the equilibrium concentration of hydrogen gas is 1.07 M

Consider the decomposition reaction of hydrogen iodide yieldinghydrogen gas (H2) and iodine vapor (I2): 2HI <=> H2 + I2 A 1Liter vessel has 2 mols of HI placed into it. The temperature isset for the decomposition to occur. After 5 days equilibrium hasbeen reached. If K is equal to 0.999, determine the number of molsof hydrogen gas seen in the reaction vessel at equilibrium.



a. 0.600 moles of hydrogen gas

b. 0.624 moles of hydrogen gas

c. 0.666 moles of hydrogen gas

d. 0.715 moles of hydrogen gas

e. 0.707 moles of hydrogen gas
