Option B.
C (activation energy) would decrease meaning that the catalyst provides an alternative path where lower activation energy is needed for a reaction to take place.
If this helps, do give this answer 5 stars and a brain lister
3
- it is a gas so not 2
- 1 is a diatomic molecule (both atoms the same)
- 4 only has 2 atoms joined in each
Expected to deal with what? Fires?
<u>Given that </u>–
<u>We know that</u> –
Then –
Now the number of moles of KOH need to ensure that concentration of Hydroxide anions is equal to –
Volume of the solution contains the need number of moles of Hydroxide anions –
