Question

the question is in the description

The first-order decomposition of N2O at 1000 K has a rate constant of 0.76 s-1. If the initial concentration of N2O is 10.9 M, what is the concentration of N2O after 9.6 s? (5 points)


A) 7.4 × 10-3 M         B) 1.0 × 10-3 M          C) 1.4 × 10-3 M          D) 3.6 × 10-3 M         E) 8.7 × 10-3 M
