Question

1. The "equilibrium condition" of a chemical reaction is in no way related to temperature. True or False

2. Of the two reactions whose equilibrium constants are 0.003 and 30, the one which will produce greater quantities of products is the one whose equilibrium constant is 0.003. True or False

3. The magnitude (size) of the activiation energy for the reverse reaction is eactly the same as the activation energy for the forward reaction. True or False

4. If a chemical reaction at an equilibrium state is disturbed, the reaction will compensate for the disturbance in some way so that equilibrium can be restored. True or False

Explanation / Answer

1. False, according with the Le Chatelier principle heat "acts" like a reactive in the case of an endothermic reaction and like a product in an exothermic reaction.

2. False, the definition of equilibrium constant is: K = [Products]/[Reactants], for more products concentration, the constant will be larger.

3. False, the activation energy depends on the enthapy of the reactants, in the reverse reaction the reactants will be the products, this make a variation in the activation energy calculated value. Rememeber:

Ea (forward) = H (activated complex) - H (reactants) and Ea (reverse) = H (activated complex) - H (products)

4. True, an equilibrium system always tends to vary the concentration ratio of the reactants and the products to establish the equilibrium.
