Problem 29P
At 100°C, Kp = 60.6 for the reaction
2NOBr(g) ⇌ 2NO(g) + Br2(g)
In a given experiment, 0.10 atm of each component is placed in a container. Is the system at equilibrium? If not, in which direction will the reaction proceed?
ANSWER:
Solution 29P:
Here, we are going to explain about the equilibrium as well as the direction of the reaction.
Step 1:
Given reaction,
2NOBr(g) ⇌ 2NO(g) + Br2(g)
Therefore, the reaction quotient (Q) in terms of pressure for the reaction is defined as
----(1)
Thus, we know that
- when Q < K, the reactants would be large relative to the products.Therefore, the reaction proceeds towards right to form more product, until equilibrium is reached.
Thus, Reactant Products, when Q < K
- when Q > K, the product would be decrease with increase in reactant. Therefore, the reaction proceeds towards left, until equilibrium is reached.
Thus, Reactant Products, when Q > K
(c) It can be happened only when the reactant and product concentrations have attained their equilibrium values.Therefore, there is no net change in the reaction.
Thus, Reactant Products, when Q = K.
