Can someone tell me what is the right answer and why? :) In the reversible reaction: H2 (g) + I2 (g) 2HI (g), an initial mixture contains 2 mol H2 and 1mol I2. The amount of HI expected at equilibrium is: (a) 1 mol; (b) 2 mol; (c) less than 2 mol; (d) more than 2 mol but less than 4 mol.

Can someone tell me what is the right answer and why? :)
In the reversible reaction: 
H2 (g) + I2 (g) <---> 2HI (g), an initial mixture contains 2 mol H2 and 1mol I2. The amount of HI expected at equilibrium is:
(a) 1 mol; (b) 2 mol; (c) less than 2 mol; (d) more than 2 mol but less than 4 mol.

this is straight stoichiometry based on the limiting reagent.  Is H2 or I2 the LR?
