Answer:
d. changing temperature
Explanation:
The thermodynamic equilibrium constant K is defined as a quantity characterizing the equilibrium of a chemical reaction. For a reaction where concentrations are in equilibrium:
aA + bB ⇄ cC + dD
The equilibrium constant is:
Thus, the equilibrium constant will change if:
a. Varying the initial concentration of reactants . FALSE. The k constant doesn't depend of initial concentrations but concentration in equilibrium does.
b. Adding other substances that do not react with any of thespecies involved in the equilibrium . FALSE. The equilibrium constant just depends of substances that are involved in the equilibrium
c. Varying the initial concentration of products . FALSE. Again, equilibrium constant doesn't depend of initial concentrations.
d. Changing temperature . <em>TRUE. </em>As a thermodynamic constant, k depends of temperature thus:
e. Changing the volume of the reaction vessel. FALSE. The changing in the volume of the reaction vessel will change just the initial concentrations of the reactants.
