A 3.00\,L container at constant temperature holds the reaction mixture for H2(g)+I2(g)⇌2HI(g). Initially the container has 0.75\,mol H2, 0.75\,mol I2, and 0.30\,mol HI. The volume is then rapidly compressed to 1.50\,L, and the temperature is kept the same. What is the value of Qc immediately after the compression?
a) 0.80
b) 0.32
c) 0.16
d) 3.2
