For the first order decomposition of N2O5 , it is found that
2 N2O5 (g) ¾® 4 NO2 (g) + O2 (g) dt−d[N2O5]= K [N2O5]
N2O5 (g) ¾® 2 NO2 (g) + 21O2 (g)dt−d[N2O5]= K¢[N2O5]
Therefore which of the following is true?
A
K = K¢
B
K > 2K¢
C
K > K¢
D
2K = K¢
Answer
K = K¢
Explanation
Solution
Rate of disappearance of N2O5 does not depend upon the way a chemical reaction is formulated. Therefore , K = K¢
