C5.2.3 - Concentration, Pressure And Reaction Rate Flashcards
1
Q
What is the concentration of a solution?
A
A measure of how much solute is dissolved in a solvent
2
Q
Why does the rate of reaction in solution increase if there is multiple reactants?
A
The more reactants there are, the more solute will dissolve in solvent which increases the concentration and causes particles to collide more often
3
Q
While investigating the reaction between magnesium ribbon and hydrochloric acid, what is the control factor?
A
The length of the magnesium ribbon
4
Q
Why does the rate of reaction in gas increase is there is multiple reactants?
A
The more reactants there are, the higher the pressure, which leads to crowded particles and more collisions
