What is the value of the activation energy of the uncatalyzed reaction?
Lubov Fominskaja [6]
The value of the activation energy of an uncatalyzed reaction is greater than that of a catalyzed reaction. As we know, a catalyst provides an alternative path for the reaction to happen at a faster rate. So, for a catalyzed reactio, activation energy is lesser than the original path.

Sulfur has an atomic number of 16 what is the ground-state electron configuration of sulfur​
guapka [62]

Answer:

1s2 2s2 2p6 3s2 3p4

Explanation:

For ground state atoms you need to fill the orbitals in order.

Orbital s has max 2 electrons

Orbital p has max 6 electrons

Level 1 only has s orbital

Level 2 has s and p orbitals

Level 3 has s, p and d orbitals

You fill them in order until you reach 16 electrons:

1s2 2s2 2p6 3s2 3p4
