#### Question 1

**Scenario:** 

Mark and Elizabeth are combining two substances, X and Y, in chemistry class. Substance X is a solid and Substance Y is a liquid. They are investigating the rate of reaction between the two substances. 

**Question:** 

In a reaction between Substances X and Y, which action would MOST likely increase the reaction rate?

**Options:** 
- A) increasing the pressure on X and Y
- B) adding more of X and Y
- C) using smaller sized particles of X
- D) lowering the temperature of Y

#### Instructions:
Please select the option that you think is correct and justifies your reasoning.
