Chapter 21: Q21.136 CP (page 978)

You are investigating a particular chemical reaction. State all the types of data available in standard tables that enable you to calculate the equilibrium constant for the reaction at298 K.

Short Answer

Expert verified

The types of data available to enable evaluate the equilibrium constant for the reaction are obtained as: ∆Ho,∆Go,∆Ecell0and∆So

Step by step solution

01

Define chemical reaction

Chemical synthesis or, alternatively, chemical breakdown into two or more separate chemicals occurs when one component interacts with another to generate new material. These processes are known as chemical reactions, and they are generally irreversible until followed by other chemical reactions.

02

Stating all the types of data available

The following reactions can be used to get the equilibrium constant:

∆Go= - nFEocell= - RTlnK∆Go=∆Ho- T∆So= RTlnK

The equilibrium constant at 298 K may be calculated using the variables ∆Ho,∆Go,∆Ecell0and∆So.

Therefore, we get:∆Ho,∆Go,∆Ecell0and∆So

What purpose does the salt bridge serve in a voltaic cell, and how does it accomplish this purpose?

In addition to reacting with gold (see Problem), aqua regia is used to bring other precious metals into the solution. Balance the skeleton equation for the reaction with Pt:

When zinc is refined by electrolysis, the desired half reaction at the cathode is:

Zn2 +(aq) + 2e-→Zn(s)

A competing reaction, which lowers the yield, is the formation of hydrogen gas:

2H+(aq) + 2e-→H2(g)

If 91.50%of the current flowing results in zinc being deposited, while8.50% produces hydrogen gas, how many litres ofH2 , measured at STP, form per kilogram of zinc?

A chemist designs an ion-specific probe for measuring [ Ag+] in an NaCl solution saturated with AgCl. One half-cell has an Ag-wire electrode immersed in the unknown AgCl saturated NaCl solution. It is connected through a salt bridge to the other half-cell, which has a calomel reference electrode [a platinum wire immersed in a paste of mercury and calomel ( Hg2Cl2)] in a saturated KCl solution. The measuredEcell is 0.060V. (a) Given the following standard half-reactions, calculate [Ag+ ].

Calomel:Hg2Cl2(s) + 2e-→2Hg + 2Cl-Eo= 0.24 V

Silver:Ag+(aq) +e-→Ag(s)Eo= 0.80 V

(Hint: Assume [ Cl-] is so high that it is essentially constant.) (b) A mining engineer wants an ore sample analyzed with theAg+ - selective probe. After pre-treating the ore sample, the chemist measures the cell voltage as V. What is [ Ag+]?
