FREE Expert Solution
H2(g) + I2(g) ⇌ 2HI(g)
The formula for the equilibrium constant Kc is simply the concentration of the products over the concentration of the reactants with the coefficient of the balanced reaction as the exponent of each concentration term.
Problem Details
Consider the following reaction: H2(g) + I2(g) ⇌ 2HI(g)
Complete the following table. Assume that all concentrations are equilibrium concentrations in M.
| T(oC) | [H2] (M) | [I2] (M) | [HI] (M) | Kc |
| 25 | 0.0355 | 0.0388 | 0.922 | – |
| 340 | - | 4.60×10−2 | 0.390 | 90.6 |
| 445 | 4.90×10−2 | 4.72×10−2 | – | 50.2 |
Find Kc at 25 oC.
