(4 cards)
1
Q

A
- concentration (of solutions)
- pressure (of gas)
- surface area (of solids)
- temp
- catalysts
2
Q
What is the effect of a catalyst on the rate of reaction + what is it like at the end of the reaction
A
- increases rate of reaction
- unchanged at end of reaction
3
Q
Practical method for investigating ror - change in mass
A
measuring the loss in mass as a gas is given off during a reaction
4
Q
Practical method for investigating ror - formation of a gas
A
Gas is collected using a gas syringe or over water in an inverted measuring cylinder
