Question

powdered calcium carbonate react more readily with hydro chloric acid than marble chips​

Answer 1

Answer:

When dilute hydrochloric acid reacts with marble chips the following

reactions occurs:

CaCO3 + 2HCL = H2O + CO2

This is the reaction we will be investigating. We will be

investigating what changes the rate of reaction.

A list of variables that could affect the rate of reaction

- Temperature

- Concentration

- Surface Area

- Temperature: This variable changes the rate of reaction, when the

temperature is increased the rate of reaction is quicker, because the

particles have more energy to move around and collide with each other.

The more collisions between particles in a given time, the faster the

rate of reaction.
