For Part a), we're being asked to determine if the second reaction in equilibrium. We're given the following reaction:
H2(g) + I2(g) ⇌ 2 HI(g)
Step 1: Calculate the equilibrium constant, Kp.
Given at equilibrium:
PH2 = 0.958 atm
PI2 = 0.877 atm
PHI = 0.020 atm.
Consider the following reaction: H2(g) + I2(g) ⇌ 2 HI(g)
A reaction mixture at equilibrium at 175 K contains PH2 = 0.958 atm, PI2 = 0.877 atm, and PHI = 0.020 atm.
A second reaction mixture, also at 175 K, contains PH2 = PI2 = 0.614 atm , and PHI = 0.105 atm.
a. Is the second reaction in equilibrium? yes/no
b. If not, what will be the partial pressure of HI when the reaction reaches equilibrium at 175 K?
