A. add a catalyst is the correct answer.
A catalyst never takes part in the reaction, so it does not affect the reaction.
Hope this helps~
Answer:
Your answer is potASSium Iodide
Explanation:
I took the test yesterday
Please give brainliest
rate 1 of the reaction = k [A]²
rate 2 of the reaction = k [A/2]² = k[A]² /4
We can see that rate of the reaction will be 4 times less.
Answer:
See explanation
Explanation:
The solar system consists of the sun at the core surrounded by all the planets in their proper order. Similarly, the Bohr model of the atom upholds Rutherford's planetary model in which the atom was said to have a positive core surrounded by electrons moving in orbits just as the planets orbit round the sun.
The difference between the two models is that electrons are able to move from one energy level to another. This assumption violates the principles of the solar system because the position of the planets are fixed in their orbits.
The theoretical basis behind this assumption is that each spectral line is produced by the transition of electrons from one energy level to another.
