Define a chemical reaction at equilibrium is heated

Reference no: EM13238661

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 cannot 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 enthalpy change cannot be determined

The enthalpy change could be negative (exothermic)

The enthalpy change could be positive (endothermic)

The sign of both the entropy and enthalpy change depends on the temperature change
