Need Help With Grade 12 Chemistry Question?
Given the following information:
Find the K200℃ value for
- OCVLv 66 years agoBest Answer
K = (c(PCl3)* c(Cl2)) / c(PCl5)
Put in the values and solve K, if K is greather than 1, the reaction will occur.
For the second question, you need to calculate all concentrations.
K = 0,042
c(PCl5) = c0 -x
c(PCl3) = c0 + x
c(Cl2) = c0 +x
K = [ (c(PCl3)+x)* (c(Cl2))+x) / (c(PCl5)-x) ]
Now solve for x, you'll get a quadratic equation. However, only one solution for x will be the right one (the other one will make the concentrations negative)
