At `445^(@)C,K_(c)` for the following reaction is `0.020`.
`2HI(g)H_(2)(g)+l_(2)(g)`
A mixture of `H_(2),I_(2)` and `HI` in a vessel at `445^(@)C` has the following concentration: ltbgt `[HI]=2.0M,[H_(2)]=0.50M` and `[I_(2)]=0.10M`. The statement that is true concerning the reaction quotient, `Q_(c)` is:

A

`Q_(c)K_(c),` the system is at equilibrium

B

`Q_(c)` less than `K_(c),` more `H_(2) "and" I_(2)` will be produced

C

`Q_(c)` less than `K_(c),` more `HI` will be produced

D

`Q_(c)` is greater than `K_(c),` more `H_(2) "and" I_(2)` will be produced
