Week 2 Climate Change/Biofuel Flashcards
1
Q
what is the enthalpy eqn
A
ΔH = energy used to break reactants - energy released in bond formation
2
Q
what are the exothermic and endothermic enthalpy conditions
A
ΔH < 0 exothermic
ΔH > 0 endothermic
3
Q
what is the activation energy
A
energy that must supplied to initiate a reaction
4
Q
what is the Arrhenius eqn
A
k = Aexp[-Ea/RT]
5
Q
what do catalysts do
A
catalysts lower activation energy
6
Q
what can be done to prevent and other effects like acid rain
A
remove impurities beforehand
catalytic convertors
ensure that catalyst is not consumed during reaction
7
Q
what is the carnot efficiency eqn
A
η = 1 - Tc/Th
8
Q
what kind of reaction is photosynthesis
A
endothermic
