Explanation:
Hello,
In this case, the reaction between sulfuric acid and hydroxide is:
We can notice a 1:2 molar ratio between the acid and the base respectively, therefore, at the equivalence point we have:
And in terms of volumes and concentrations:
So we compute the molarity of sulfuric acid as shown below:
Best regards.
Answer:
A catalyst decreases the activation energy of a reaction.
Explanation:
A catalyst allows a reaction to go through a new pathway that has a lower activation energy. Therefore, it will recquire less energy to reach the transition state (activated complex) which increases the rate of the reaction. This is the reason why adding a catalyst makes a reaction faster.
The figure attached shows the graphical representation of the effect of a catalyst on the activation energy.
