<u>Solution and Explanation:</u>
[La3+] = 0.1 M
<u>At the equilibrium: </u>
La(IO3)3 <----> La3+ + 3 IO3-
0.1 +s 3s
Since Ksp is small, s can be ignored as compared to the 0.1
The above shown expression thus becomes:
<u>Answer: 1.4*10^-4 M </u>
Answer:
The activation energy of the reaction is 1.152 kJ/mol.
Explanation:
Activation energy is the minimum amount which is absorbed by the reactant molecules to undergo chemical reaction.
Initial temperature of reaction =
Final temperature of reaction =
Initial rate of the reaction at 100 k =
Final rate of the reaction at 200 k =
Activation energy is calculated from the formula:
R = Universal gas constant = 8.314 J/ K mol
