Question

Write the letter T or F inside each box after deciding which statement is true or false. Then on the 3rd box, write the letter of your choice based on the given instructions.

          A if both statements are true

          B if the 1st statement is false and the 2nd statement is true

          C if the 1st statement is true and the 2nd statement is false

          D if both statements are false

4. Compounds formed from their elements in exothermic reaction have negative AH
lonic compounds usually have more negative enthalpies of formation.
5. Thermodynamics can tell us the direction and extent of a reaction but tells nothing about the speed
of a reaction.
Majority of spontaneous reactions are exothermic especially in irreversible reactions.
6. Enthalpy provides a quantitative measure of how much energy is spread out when something
happens.
Entropy is associated with the second law of thermodynamics.
