A temperature change in a reaction indicates a chemical change
Answer:
The answer is Option a, that is "−9kJmole,5kJmole".
Explanation:
Please find the complete question in the attached file.
In the question, it uses the catalyst inside a process, which does not modify the process eigenvalues, however, it decreases the active energy with an enthalpy of -9kJmole, and also the power for activating decreases around 13 to 5 kJ mole, that's why the choice a is correct.
Electrical engineers are the scientists that study the production of electricity more efficient.
<h3>
Which type of scientist would study how electricity could be produced more efficiently?</h3>
Electrical engineers are the type of scientist that would most likely study how electricity could be produced more efficiently because they produced new technologies which are cost efficient as well as produce high amount of electricity.
So we can conclude that electrical engineers are the scientists that study the production of electricity more efficient.
