Concentration
The ratio of solute in a substance’s total solution and/or solvent
Solvent
A substance into which thing dissolve
Rate of Reaction Formula
Change over time
Solute
Dissolves into something else
Rate of Reaction
Solid
A state of matter where there is a strong force of attraction between particles, which holds them close together in fixed with a lattice arrangement.
Steep slope means on a ROR graph…
mean higher ROR
A shallow slope on a ROR graph…
means a low ROR
Collision theory
What the ROR depends on (Correct Orientation and enough energy [like the fair height minimum)
Things that impact ROR
Surface Area, Temperature, Concentration (or the pressure of a gas) and/or catalyst.
How does SA impact the ROR?
The ratio of the SA to Volume leads to more area in order to have more frequent collisions.
How temperature
Activation Energy
The minimum amount of energy to lead to a collision
Lattice arrangement
Some solids structure that are 3D + with a crystal-like pattern
Tangent
A line that only intersects with on point on the trendline/any line
Trend line
The slope of a graph
Slope formula
y^2-y^1=x^2-x^1§
Exothermic
Exothermic reaction releases energy from bonds
Endothermic
endothermic reactions absorb energy (energy in endothermic is heat)
Pressure
Amount of force per area (in gas: how much the gas is hitting the container)
Pressure in concentration for…
gases
Temperature is…
How fast the particles move in a state of matter.
What are ions
The compounds of metals and non-metal
Molecules
Non-metals + non-metals compounds
Covalent molecules
A specific set number of atoms in molecules
Giant covalent lattices
An undefined set of atoms in molecules
Metallic compounds
Metal + metal compounds
Physical Properties
Colour,
What are reversible reactions?
conversion of reactants to products and the conversion of products to reactants occur
Equilibrium
reversible chemical reaction in which no net change in the amounts of reactants and products occurs
