Answer 1

Because the plot is a straight line:
It is first order rate law

Because y axis has natural log of A:
The unit of y is none.

Becuase unit on x axis is seconds:
The unit on x are seconds.

The general equation of a line is, y = mx + c , where m is the slope, so:
The slope of the best fit line is -0.0049.

Slope is given by , and y is unit less and x is sec, so:
The unit of the slope is 1/sec.

dy

The general equation of a line is, y = mx + c , where c is the intercept, so:
The intercept of the best fit line is -2.3.

The intercept is unitless as it is intercepting y axis:
The unit of the intercept is none.

The rate constant is the slope, so:
The unit of the rate constant is 1/sec.
