c) Speeds up the rate of reaction
d) Slows down the rate of reaction
e) None of the Above

Answer 1

The answer is b product

Answer 2

b) Product

c) Combustion

c) speeds up the rate of reaction

Step-by-step explanation:

the substance produced by a chemical reaction is called a product (b)

Combustion (c) reactions are involving oxygen and "another substance" [and hydrocarbons] to produce carbon dioxide and water.

A catalyst acts to speed up the rate of a reaction (c)

> note how it "speeds up" reaction: , it [a catalyst] lowers the pressure or temperature needed to start one--but it isn't used/consumed in the reaction

So, the answers are: b, c, c

hope this helps!!
