Catalyst and rate

Question 1

What is an catalyst

Answer 1

something that increases rate of reaction, is not used up in the reaction, doesn’t produce more product overall

Question 2

How does a catalyst work

Answer 2

provides a different pathway for the reaction -> that has a lower activation energy -> more product forms per second -> rate of reaction increases

Question 3

Biological catalysts

Answer 3

enzymes

Question 4

In a catalyst reaction profile which is the higher line (with or without catalyst)

Answer 4

without as it has more activation energy
