Answer : Option 2) providing an alternate reaction pathway that has a lower activation energy


Explanation : When a catalyst is added to a chemical reaction it increases the rate of reaction by lowering the energy of activation. It provides an alternate pathway for a reaction to proceed with a lower Ea energy. Usually a catalyst never gets consumed in the reaction process. It will appear in the reaction mechanism steps but not in the overall reaction like reactants and products.

Which statement is true about molecule speed? (1 point)
ANTONII [103]

Faster molecules have fewer collisions than slower molecules is True about molecular speed.

<h3>What is Molecular speed?</h3>

Molecular speed refers to the average distance gases or molecules travelled atca particular time rate.

It is valid in ideal gas, where the molecules do not interact with others.

Average molecular speed = Square root (3 (ideal gas constant) * (Temperature)/m)

Therefore, Faster molecules have fewer collisions than slower molecules is True about molecular speed.

Learn more about molecular speed from the link below.

Write the complete balanced equation for the reaction between barium metal (Ba) and nitrogen gas (N2). You do not need to make t
hichkok12 [17]

3Ba + N2 -----> Ba3N2


Ba is in the second group and metal, its charge = +2 in the compound.

N is non-metal, it is in 15th group, so it has 5 electrons on the last level, so it can take 3 electrons more(8-5=3). N has charge (-3) in compound.

Ba and N form compound Ba3N2.
