Question

The following reaction was monitored as a function of time AB rightarrow A + B A plot 1/[AB] versus time yields a straight line with slope 5. 7 x10 -2(M . s)-1 What is the half-life when the initial concentration is 0. 56M? Express your answer using two significant figures. If the initial concentration of AB is 0. 290M , and the reaction mixture initially contains no products. What are the concentration of A and B after 70s? Enter your answers numerically separated by a comma. Express your answers using two significant figures.

Explanation / Answer

half life t1/2 = c?/(2*k) 0.56/(2*5.7E-2) 4.912
