Question 18 The decomposition of a single compound at 363 K has a rate constant of 3.23 x 103 M s1. If the initial concentration of the reactant is 2.067 M, what is the concentration of the reactant after 79.97 seconds? (the answer should be entered with 3 significant figures; do not enter units; give answer in normal notation-examples include 1.23 and 12.3 and 120. and -123) Moving to another question will save this response.
