The following is kinetic rate data taken as absorbance of reactant vs. time:

A: ln(A): Time/min:
0.532 ?? 0.0
0.484 2.54
0.442 5.12
0.395 8.35
0.350 11.95

fill in the ln(A) column

To fill in the ln(A) column, we need to take the natural logarithm of the values in the A column. The natural logarithm (ln) of a number is the exponent to which the base (e ≈ 2.71828) must be raised to obtain that number.

Using a calculator or software that has a logarithm function, we can calculate the ln(A) values. Here are the calculations for each value in the A column:

ln(0.532) ≈ -0.6316
ln(0.484) ≈ -0.7246
ln(0.442) ≈ -0.8177
ln(0.395) ≈ -0.9296
ln(0.350) ≈ -1.0498

So, the completed ln(A) column would look like this:

A: ln(A): Time/min:
0.532 -0.6316 0.0
0.484 -0.7246 2.54
0.442 -0.8177 5.12
0.395 -0.9296 8.35
0.350 -1.0498 11.95
