A flask is charged with 0.124 mol of A and allowed to react to form B according to the reaction A(g) →B(g). The following data are obtained for [A] as the reaction proceeds:

Time (s) 0.00 - 10.0 - 20.0 - 30.0 - 40.0
Moles A 0.124 - 0.110 - 0.088 - 0.073 - 0.054

The average rate of disappearance of A between 10 s and 20 s is mol/s.

A) 2.2 × 10⁻³
B) 1.1 × 10⁻³
C) 4.4 × 10⁻³
D) 454
E) 9.90 × 10⁻³
