0.245M

Explanation:

2SO3g --> 2SO2g + O2g

Rate Constant, k = 14.1 M-1s-1

Initial Concentration, Ao = 1.44M

Final Concentration, A = ?

time = 0.240s

The integrated rate law for second order reactions relating these parameters is given as;

1 / [A] = kt + 1 / [A]o

1 / [A] = (14.1 * 0.240) + 1 / 1.44

1 / [A]  = 3.384 + 0.694 = 4.078

[A]  = 1 /  4.078 = 0.245M
