Worked Solution & Example Answer:One change was made to the equilibrium system at time $t_1$, which altered the equilibrium constant - VCE - SSCE Chemistry - Question 28 - 2021 - Paper 1
Step 1
Equilibrium constant:
Answer
The equilibrium constant is dependent on temperature and the nature of the reaction. If the equilibrium was re-established and the rate of the reverse reaction is increased, it indicates that the reaction will favor the products over the reactants, leading to a decrease in the equilibrium constant from time to .
Step 2
Total chemical energy:
Answer
As the equilibrium shifts to favor the products due to the increased rate of the reverse reaction, the total chemical energy of the system will also decrease. This is because the formation of products typically results in a release of energy compared to the reactants, thus suggesting a decrease in total chemical energy due to the favored reverse reaction.
