hydrochloric acid and marble chips

Investigating the effect of increasing
Concentration on the rate of reaction.


Prediction:

Effect of Concentration
Quantitative (doubling the concentration)

Theory:

Justify prediction using Scientific Knowledge
Effect of Concentration
What’s needed for a reaction to start
Reaction Profile

Factors which effect rates:

Theory - factor and explain in terms of particles and collisions.

Precision and Reliability:

How will you control factors (fair test)
Explain
Displacement (air/gas)
Accurate to 1 cm³ explain why
Same batch of acid - why?
Repeats
Equipment list
Diagram
Investigation Method
Symbol Equation

How Preliminary work informed planning:

Final Condition for the investigation
How did we get to this - what has changed and why?
How many results - How many needed to be precise and reliable
Both Concentration ...
