reaction temps Flashcards
1
Q
what does every chemical reaction involve
A
energy changes
2
Q
why is energy needed
A
to break chemical bonds and be released when they are made
3
Q
what is an exothermic reaction
A
where more energy is released than bonds being made
= net energy released
4
Q
what is an endothermic reaction
A
more bonds are made than broken
= net energy input
5
Q
in an exothermic reaction profile, which is higher
A
the reactants are above the products
6
Q
in an endothermic reaction profile . which is higher
A
the pro cuts are higher than the reactants
7
Q
what is the hump in a reaction profile
A
the activation energy
8
Q
what is activation energy
A
minimum amount of energy needed to start a reaction
9
Q
what is the diff between R and P
A
the change in enthalpy
10
Q
draw me both reaction profiles
A
