5 Energy In Reactions Flashcards
1
Q
What does bond breaking and bond making have in relation with energy
A
Breaking need energy
Making releases energy
2
Q
Why are energy given out to the surroundings in endothermic reactions
A
More energy is released from the bonds in the products Than is absorbed breaking the bonds in the reactants
3
Q
How do you calculate the overall energy change for a reaction from given bond energies
A
Energy of bond breaking-energy of bond making
4
Q
What do you use to calculate the amount of energy absorbed when bonds are broken or released when bonds are made
A
Bond energy
5
Q
Why are endothermic reaction is absorbing energy from the surroundings
A
More energy is absorbed breaking the bonds in the reactants Than is released forming the bonds in the product
