Question 1:
Using the ICE table
A | B | C | |
Initial | 0.830 | 0.830 | 0 |
Change | -x | -x | +x |
Final | 0.830-x | 0.830-x | x |
Solving the quadratic equation we get
Hence the partial pressure of gas C at equilibrium will be 0.782 atm
Question 2:
Using the ICE table
[HIO3] | [H+] | [IO3-] | |
Initial | 0.570 | 0 | 0 |
Change | -x | +x | +x |
Final | 0.570-x | x | x |
Solving the quadratic equation we get
[H+] = 0.238 M
