Q

temperature

A
  • increasing the temp will increase the rate of reaction

- increases the speed of the particles therefore will collide more frequently

12
Q

concentration

A

refers to the amount of particles present
increasing concentration will increase the rate of reCtion
- more particles present - more likely to collide

Q

catalysts

A
  • chemicals that speed up reactions but are not used up

- reduce the amount of energy required to convert reactants to products

HNO3
27
sulfuric acid
H2SO4
28
phosphoric acid
H3PO4
29
hydrogen peroxide decomposition
h202 - h2o + o2 + is on the other side
30
fuel combustion
CH4 +o2 - co2 + h2o
31
law of conversion of mass
- mass is not created or destroyed | - mass of the products must be equal to the reactants
32
electroplating
process of costing a metal with a thin layer of another metal by electrolysis to improve the metals corrosion resistance
33
reaction rate
determines how fast or slow the reaction is
34
reaction time
time taken to complete a reaction to a certain extent
35
surface area
increasing surface area there are more collisions per unit | cursing things before the experiment
36
pressure
- increase the pressure by forcing them into a smaller space - collide more frequently
37
acid + base
- salt + water
38
reactivity series
