Consider the following reaction. It is occuring in a closed system and it is currently at equilibrium:

2H2O(g) + Heat ↔ 2H2(g) + O2(g)  


Label each of the following statements with is effect on the reaction
(shift towards products, shift towards reactants or no change) 1. Removing hydrogen gas.
(shift towards products, shift towards reactants or no change) 2. Decrease the pressure on the reaction vessel
(shift towards products, shift towards reactants or no change) 3. Placing the reaction vessel in an ice bath
(shift towards products, shift towards reactants or no change) 4. Increase the size of the vessel.
(shift towards products, shift towards reactants or no change) 5. Removing water vapor from the vessel.

Solutions

Expert Solution

1)
Removing product will shift the reaction in the direction of product as per Le chatelier Principle
So, Equilibrium moves to product side
Answer: shift towards products

2)
Decrease the pressure will shift the reaction in a direction which have greater gaseous molecules as per Le chatelier Principle
Here product has more gaseous molecule
So equilibrium will move to right
So, Equilibrium moves to product side
Answer: shift towards products

3)
Decreasing Temperature will shift the reaction in a direction which release heat as per Le chatelier Principle
Forward reaction is endothermic in nature
hence, backward reaction will be favoured
So, Equilibrium moves to reactant side
Answer: shift towards reactants

4)
Increasing volume will decrease the pressure which in turn shift the reaction in a direction which have greater gaseous molecules as per Le chatelier Principle
Here product has more gaseous molecule
So equilibrium will move to right
So, Equilibrium moves to product side
Answer: shift towards products

5)
Removing reactant will shift the reaction in the direction of reactant as per Le chatelier Principle
So, Equilibrium moves to reactant side
Answer: shift towards reactants

Shown below is the overall reaction occuring in the direct methanol fuel cell (DMFC). CH3OH(aq) + O2(g) → CO2(g) + H2O(l) (not balanced!) Balance the reaction using the half-reaction method. It may be useful to work out the oxidation states of the reactants and products. First, show the balanced (half-)reaction that occurs at the anode. Next, show the balanced (half-)reaction that occurs at the cathode. Now, show the overall, balanced reaction.

Consider the reactor system shown below. The reaction is exothermic so a cooling system is provided to remove the excess energy of the reaction. In the event that the cooling function is lost, the temperature of the reactor would increase. This would lead to an increase in reaction rate, leading to an additional energy release. The result would be a runaway reaction with pressures exceeding the bursting pressure level of the reactor vessel. The temperature within the reactor is measured...
