Final answer:
The validity of several statements about a reaction in a flask charged with H2S is evaluated, providing explanations for each statement.
Step-by-step explanation:
The given question is about evaluating the validity of several statements pertaining to a reaction in an empty flask charged with H2S at a certain temperature. Let's go through each statement:
a) no reaction occurs. False. Since the flask is charged with H2S, a reaction will occur.
b) the pressure of ammonia is zero. True. Since there is no ammonia in the flask, the pressure of ammonia is indeed zero.
c) Q is greater than K. False. The reaction quotient Q is calculated by substituting the initial concentrations or pressures of the reactants and products into the equilibrium expression. If Q is greater than K, the reaction will proceed to the left. If Q is less than K, the reaction will proceed to the right. If Q is equal to K, the reaction is at equilibrium.
d) the reaction proceeds to the left. False. Based on the information given, we cannot determine the direction in which the reaction proceeds.
e) Q is equal to 0. False. Since the flask is charged with H2S, there will be a non-zero value for Q.
f) the reaction proceed to the right. True. Since the flask is charged with H2S, the reaction will proceed to the right.
