2. 2. Consider the following reaction occurring in a closed chemical system. Assume that this reaction is at equilibrium and tha

t in general the reaction to the right is favored. CH3CH2OH + 3O2 2CO2 + 3H2O ∆H = –1,235 kJ/mol • What type of chemical reaction is this? • If more CH3CH2OH is added to the system, how will the reactions shift to reach equilibrium again? • If water is extracted from the system, how will the reactions shift to reach equilibrium again? • If heat is removed from the system, how will the reactions shift to reach equilibrium again? • What is the name of the principle that helps you predict each of these shifts in equilibrium?

Answer:

This is an exothermic reaction.

The equilibrium will shift to the right to consume the reactant and counter this change.

The equilibrium will shift to the right to produce more water and counter this change.

The equilibrium will shift to the right to produce more heat and counter this change.

This is known as Le Chatelier's principle and it states that when a change is produced in an equilibrium system, the system will shift in a manner so as to counteract the change.

1. This is a combustion reaction.<span>

<span>Combustion reactions can happen with the </span>presence of O</span>₂ <span>gas. O₂<span> reacts with another element or compound and </span></span>oxidize<span> it. Here ethanol reacts with O₂<span> and produces </span></span>CO₂ and H₂O as products.<span> <span>Combustion is also called as </span></span>burning. <span>

2. Reaction will shift to right. <span>

</span><span>If more CH</span>₃CH₂OH is added to the system, then the</span> amount of CH₃CH₂OH will increase.<span> <span>Then the equilibrium in the system </span></span>will be broken.<span> <span>To make the equilibrium again, the </span></span>added CH₃CH₂OH should be removed.<span> To do that system will consume more CH</span>₃CH₂<span>OH to make products which helps to decrease the amount of ethanol. Hence, the reaction will shift to right.<span>

3. The reaction will shift to right.</span><span>

</span><span>If the water is extracted from the system, the </span>amount of water will decrease. <span>That means the </span>amount of products decrease. Then the system will try to gain equilibrium by increasing the water. To increase water the forward reaction should be enhanced. <span>Hence, the</span> reaction will shift to right.<span>

4. The reaction will shift to right.

</span><span>This is an </span>exothermic reaction <span>since it </span>produces heat. If the produced heat is removed, then the system will be cold. To maintain the temperature, system has to increase the amount of heat produced. Then, the forward reaction should be enhanced. Hence, the reaction will shift to right.<span>

5. The Le Chatelier's principle.

</span>Le Chatelier's principle says if a condition changes in a system which was in an equilibrium state, the system will try to gain equilibrium by correcting the changed condition back to normal. Most of industries which make chemicals use this principle</span>

this shows that magnesium is higher in the reactivity series than lead.

I don't think there can be an ionic equation written because both components are in solid form and neither is in an aqeuos state.
