A chemical reaction at equilibrium is heated, briefly, by holding it over a flame. The equilibrium is seen to shift toward the products. What can be said about the enthalpy and entropy of the reaction?
- We can not determine the sign or the value of the entropy change
- The entropy change must be negative, but we don't know the value
- The entropy change must be positive, but we don't know the value
- The entropy change can not be determined
- The enthalpy change could be negative( excothermic)
-The enthalpy change could be positive( endothermic)
-The sign of both the entropy and enthalpy change depends on the tempreature change.
