Problem- A 35.0-L vessel at 700 K initially contains HI(g) at a pressure of 6.90 atm; at equilibrium, it is found that the partial pressure of H2(g) is 0.668 atm.
What is the partial pressure of HI(g) at equilibrium? 2HI(g) <---> H2(g) + I2(g)
Choose one of these.
6.90 atm
6.23 atm
0.668 atm
5.56 atm
7.57 atm
