Calculating K - Problem 3

0.25 mol of NOCl was initially in a 2.0 L container at 500 ºC. After equilibrium it is found that the concentration of NOCl has dropped to 0.090 mol/L.

1.To solve this problem you should use an IRE table something like the following.

a) What is the initial concentration of NOCl (press [Check I])?
b) Complete the reaction row with appropriate values, then press the [Check R] button.
c) Complete the equilibrium row with the appropriate values, then press the [Check E] button.

Remember that you type numbers in scientific notation like 1.234E-05 for 1.234x10^-5
