Introduction To Equilibrium

If the concentration of OH ' ions in the reaction

For the reaction at 298 K, is found to be . If the concentration of at equilibrium is 0.040 M, then the concentration of in M is:

1.
2.
3.
4.

The equilibrium concentration of the species in the reaction are 2, 3, 10 and 6 mol L^–1, respectively at 300 K. for the reaction is:
(R = 2 cal/mol K)

1.	–13.73 cal	2.	1372.60 cal
3.	–137.26 cal	4.	–1381.80 cal

Consider the following reaction in a sealed vessel at equilibrium:

[Given: and ]

If 0.1 mol L^-1 of NO_(g) is taken in a closed vessel, what will be the degree of dissociation ( ) of NO_(g) at equilibrium?
1. 0.0889
2. 0.00717
3. 0.717
4. 0.00889
