Chapter 1, Problem 1.89SP

An experiment is performed to determine if pennies are made Of pure copper. The mass of 10 pennies was measured on a balance and found to be 24.656 g. The volume was found by dropping the 10 pen- nies into a graduated cylinder initially containing 10.0 mL of water. The volume after the pennies were added was 12.90 ml,. Calculate the density of the pennies. If the density of pure copper at the same temperature is 8.96 g/ cm3, are the pennies made of pure copper?

The data for the potential difference of a battery and its temperature are given in the table. Calculate the entropy change in J mol-1 K-1 (indicate the formulas used).Data: F = 96485 C mol-1
In a cell, the change in entropy (AS) can be calculated from the slope of the E° vs 1/T graph. The slope is equal to -AS/R, where R is the gas constant. Is this correct?
Using the Arrhenius equation, it is possible to establish the relationship between the rate constant (k) of a chemical reaction and the temperature (T), in Kelvin (K), the universal gas constant (R), the pre-exponential factor (A) and the activation energy (Ea). This equation is widely applied in studies of chemical kinetics, and is also widely used to determine the activation energy of reactions. In this context, the following graph shows the variation of the rate constant with the inverse of the absolute temperature, for a given chemical reaction that obeys the Arrhenius equation. Based on the analysis of this graph and the concepts acquired about the kinetics of chemical reactions, analyze the following statements:              I. The activation energy (Ea) varies with the temperature of the system.   II. The activation energy (Ea) varies with the concentration of the reactants.        III. The rate constant (K) varies proportionally with temperature.    IV. The value of the…
