Question

An increase in the temperature increases the rate of a chemical reaction becuase the collsisons in this reaction increase in
a) number only
b)effectiveness only
c) both number and effectiveness
d) neither

Answer 1

both

Answer 2

the reaction A(g) + B(g) ----> C(g) + D(g) +30 KCal has a froward activation energy of 20 kcal . What is the activiation energy for the reverse reaction ?

Answer 3

fitty

Answer 4

sorry switch the 20 and the 30

Answer 5

so the 20 would be the activated complex and 30 would be the activation energy or potential energy?

Answer 6

30 would be energy released by the reaction because it's exothermic, it's all potential energy

Answer 7

activation complex is the state of the molecule, activation energy is the energy necessary for the molecule to achieve that state

Answer 8

which reaction would have the lowest activation energy 1) the forward catlayzed reaction
2) the reverse catalzyed reaction
3) the forward unctalyzed reaction
4) the reverse uncatalyzed reaction

Answer 9

which one has lower activation energy forward or backward?

catalyzed activation energy is always lower

Answer 10

can you explain to me the basics of lechtaliers principle espeically involving pressure , concentration, and temperature and what direction does the stress of the equillibrium direction of both the forwards and reverse reaction . Pleas explain it as simpa and basic as you can I have an exam tomorrow HELP!!!
