Chemistry

The reaction A → B + C is known to be first order in A. Beloware data showing the concentration of A as a function of reactiontime.

Time, h[A], M
0.55.00 x 10-2
14.51 x 10-2
24.06 x 10-2
33.30 x 10-2
42.18 x 10-2
51.77 x 10-2
61.44 x 10-2

(a) What is the average rateof reaction between 0.5 and 2 h? Report the units as well as thenumbers.

(b) Plot the data above, showing theconcentration of A as a function of the time. From your graph,determine the instantaneous rate of reaction at 4h. Report the units as well as the numbers.

(c) Plot ln [A] versus time. Estimate the rateconstant for this first-order reaction from your graph. Report theunits as well as the numbers.
