y = -0.02735x-2.3026 -2.4 -2.6 -2.8 -3.0 10 15 20 25 30 Time (s) In((A])


Expert Answer

Step 1

From the given data,

The graph between ln [A]  vs  time is a straight line.

This indicates that the given hypothetical reaction is of first order.

Step 2

The given equation is:

y = - 0.02735 x - 2.3026

which is in the form of y =mx +c 

The slope of the line m = -0.02735 

We know that : m=-k
