Chapter 2, Problem 2.32P
Interpretation Introduction

(a)

Interpretation:

The units of 3.00 and 2.00 should be determined.

Concept introduction:

A concentration C (mol/L) varies with time (min) according to the equation.

C=3.00exp(2.00t)

It is assumed that the given equation is valid and therefore dimensionally homogeneous. So, the dimension of the left hand side and right hand side of the equation is equal. In addition, the exp () component is dimensionless.

Interpretation Introduction

(b)

Interpretation:

Suppose the concentration is measured at t=0 and t=1 min. Use two-point interpolation or extrapolation to estimate concentration at t=0.6 min and time at C= 0.1 mol/L.

Concept introduction:

A concentration C (mol/L) varies with time (min) according to the equation.

C=3.00exp(2.00t)

The two endpoints of a linear graph are assumed to be (x1, y1) and (x2, y2) and extrapolation should be done for the value of the point x, then for extrapolation, the formula is given by,

y(x)=y1+xx1x2x1(y2y1)

Interpretation Introduction

(c)

Interpretation:

A curve of C versus t should be sketched.

Concept introduction:

A concentration C (mol/L) varies with time (min) according to the equation.

C=3.00exp(2.00t)
