The equilibrium constant for some reactions are given below against each of the reaction:
(i) 2N2 + O2 ⇌ 2N2O; K = 4 × 10-36
(ii) N2 + O2 ⇌ 2NO; K = 1 × 10-30
(iii) N2 + 2O2 ⇌ 2NO2; K = 9 × 10-38
Which of the following statement is correct?
Options:(select one or more)
Answer:
A, B
Solution:
Each reaction forms 2 mol of oxide from the elements, so a larger K means a more stable oxide KNO = 1 × 10-30 is the largest
KN2O = 4 × 10-36 is next
KNO2 = 9 × 10-38 is the smallest
Stability order is NO > N2O > NO2, so (a) and (b) are correct and (c), (d) are incorrect
The correct options are (a) and (b).
