- C \(A = -B\)
- D \(A = -2B\)
Answer & Solution
Correct Answer
(A) \(A = B\)
Step-by-step Solution
Detailed explanation
If \(A = \begin{vmatrix} a & d & l \\ b & e & m \\ c & f & n \end{vmatrix}\) and \(B = \begin{vmatrix} l & m & n \\ a & b & c \\ d & e & f \end{vmatrix}\) Matrix A is formed by taking columns (a,b,c),(d,e,f) (l,m,n) So, B is obtained from A by cyclic permutation of rows and then…

The decomposition of \(N_2O_5\ (g)\) is given as
\(N_2O_5(g) \rightarrow 2NO_2(g) + \frac{1}{2}O_2(g)\)
The above reaction is found to be of first order.
The initial concentration of \(N_2O_5\) was \(1.24 \times 10^{-2}\ M\) at \(318\ K\).
The concentration \(N_2O_5\) after \(60\ minutes\) was \(0.20 \times 10^{-2}\ M\).
