Which situation would cause the following equilibrium reaction to decrease the formation of the products? 2SO2 (g) + O2 (g) Two
vovangra [49]

The given equilibrium reaction is,

2 SO_{2} (g) + O_{2}(g)  2 SO_{3} (g) + Energy

The given reaction is exothermic. So, heat energy will be a product. Therefore, decreasing the temperature (heat energy) would lead to the formation of more products as when the amount of energy which is a product is reduced, there is more room for the products to form.

Increasing the pressure would shift the equilibrium towards that side which has least number of moles of the gaseous substance. Hence, here increasing the pressure would lead to the formation of more products by shifting the equilibrium towards the right side.

Decreasing the volume would make the equilibrium shift towards the least number of moles of the gaseous substance. So, here in this equilibrium decreasing the volume would lead to the formation of more products.

Two voltaic cells are to be joined so that one will run the other as an electrolytic cell. In the first cell, one half-cell has
stiks02 [169]

Au³⁺ metal ion is reduced in the Au/Cr cell and Co²⁺ metal ion is reduced in the Co/Zr cell

<h3>What is a voltaic cell?</h3>

A voltaic cell is a cell that generates electricity by a spontaneous redox reaction.

It is an electrochemical cell, also known as a galvanic cell and  

Electrical energy is created by converting chemical energy.

Examples of voltaic cells include the dry cell, nickel-cadmium cell, lead storage cell, and fuel cells.

The half-cell reactions for each cell are given by

Au^{3+}(aq) + 3e^- \rightarrow Au(s) ; E° = 1.50 V

Cr^{3+}(aq) + 3e^- \rightarrow Cr(s) ; E° = –0.74 V

Co^{2+}(aq) + 2e^- \rightarrow Co(s) ; E° = –0.28 V

Zn^{2+}(aq) + 2e^- \rightarrow Zn(s) E° = –0.76 V

Thus, Au³⁺ is reduced in the Au/Cr cell and Co²⁺ is reduced in the Co/Zr cell
