Answer: = 42.9 atm,
= 93.4 atm and
= 7.66 atm
Explanation: The given balanced equation is:
Initial pressure of = 50.560 atm
initial pressure of = 50.500 atm
Let's say the change in pressure is p. Then:
equilibrium partial pressure of = (50.560 - p) atm
equilibrium partial pressure of = (50.500 + p) atm
equilibrium partial pressure of = p atm
Let's plug in the values in it:
on cross multiply:
on rearranging the above equation:
It's a quadratic equation. On solving this equation:
p = 42.9
So, the equalibrium partial pressure of = 42.9 atm
equilibrium partial pressure of = 50.500 + 42.9 = 93.4 atm
equilibrium partial pressure of = 50.560 - 42.9 = 7.66 atm
