What is the collision theory?
a theory to do with atoms moving as quick as cars
states that atoms, ions and molecules must collide in order to react
that reactants that bump into each other will always rebound
Which condition is not needed for a successful collision of reactant molecules to form a product?
correct orientation
reactants must collide
reactants need enough energy upon collisions
must be heated to at least 373K
What the Activation energy?
The maximum energy a reaction can release
The minimum amount of energy that reacting particles must have when colliding to form products
The energy added by a catalyst
The energy possessed by the products
A high activation energy means the rate of the reaction will be...
fast
slow
medium
When we investigate the rate of reaction we are looking at the...
amount of product formed
speed of reaction
concentration of reacting particles
combining reactants with products
Endothermic reactions...
absorb energy to reach the activation energy to form products
release energy when products are formed
need an electronegative element involved
An Exothermic react released energy when new products are made. What would the energy diagram look like?
Curve goes low to high
Curve goes high to low
