Catalyst is a substance that speeds up the rate of any chemical reaction but they do not take part in the reaction.
<h3>What is a catalyst</h3>
Catalyst is a substance that speeds up the rate of any chemical reaction but they do not take part in the reaction.
Catalysis is the process of increasing the rate of a chemical reaction by the addition of a substance known as a catalyst.
Catalysts are known not to be consumed in the reaction and remain unchanged at the end of a reaction

Answer:

Step-by-step explanation:
exponential function : 
where a = y intercept and b = factor ( what you multiply by )
looking at the table the y intercept is at (0,10) so a = 10
so we now have y = 10 * (b)^x
to find the factor we simply plug in one of the ordered pairs.
note that the ordered pair chosen does not effect the outcome
i chose (2,250)
we have y = 10 * (b)^x
(x,y) = (2,250)
250 = 10 * (b)^2
divide both sides by 10
25 = b^2
take the square root of both sides
5 = b
the final equation would be f(x) = 10 * (b)^x
