When a sample of NO2(g) (5.641 mol) is placed in 360.0 L reaction vessel at 716.0 K and allowed to come to equilibrium the mixture contains 3.412 mol of NO(g). What is the equilibrium concentration (mol/L) of NO(g)?

When a sample of PCl5(g) (1228 grams) is placed in 270.0 L reaction vessel at 906.0 K and allowed to come to equilibrium the mixture contains 2.079 mol of PCl3(g). What concentration (mol/L) of PCl5(g) reacted?

what is the difference between equilibrium concentration and concentration reacted

  • chemistry(just need to clarify, no need to solve) - ,

    A+B><C+D

    A and B are reacting to make C and D. C and D are reacting to make A and B. When the reaction rates both ways are the same, or equal, the reaction is said to be in equilibrium. The equilibrium concentrations are the moles of A, B, C, and D divided by the volume.

    This is not the initial concentration. Pretend you had some A, some B, and Some C, and no D. You have then four intial concentrations (one zero). The reaction proceeds to a final equilibrium, and reaches concentrations of A, B, C, D as determined by conditions. The amount reacted is different than the initial amount, and in fact, it can be + or -, as it could be less or more than was present initially.
