Answer:
Explanation:
Hello,
In this case, for the given reaction at equilibrium:
We can write the law of mass action as:
That in terms of the change due to the reaction extent we can write:
Nevertheless, for the carbon monoxide, we can directly compute as shown below:
Finally, we can compute the equilibrium constant:
Best regards.
Answer:
The balanced half-reaction for the reduction of dichromate ion to chromium ion in acidic aqueous solution:
Explanation:
The reaction :
Balancing of reaction in an acidic medium:
Step 1: Balance the atoms in the reaction:
Step 2: Balance oxygen atom by adding water on the side where no oxygen or less oxygen atom is present;
Step 3: Balance the hydrogen atom by adding hydrogen ions on the side where water is absent:
Step 4: Now balance charge by adding electrons on the side where more positive charge is present
The balanced half-reaction for the reduction of dichromate ion to chromium ion in acidic aqueous solution:
Answer:
It is <u>melting</u> which is a physical change.
