Question

Consider the following equilibrium: Suppose Q = 1.64. Which of the following statements is correct? A) Because Q = 1, the system, is at equilibrium. B) Because Q = 1, more reactants will be formed. C) Because Q K, more reactants will be formed. For a certain reaction of the general form aA rightarrow products, a plot of the versus time is linear. What is the reaction order with respect to reactants A) zero B) first C) third D) fourth E) second For the hypothetical aA rightarrow products, the experimental data (below). What is the reaction order with respect is reactant A? A) zero-order B) second-order C) third-order E) fourth-order

Explanation / Answer

Ans 1. As Kc = 9.57 that means the concentration of product is more than the concentration of reactants. and hence

ans because Qc < Kc, more product will be formed.

Ans 2. (a) zero order reaction

For zero order reaction, a plot of rate of reaction w.r.t time is linear.

Ans 3. (c) first order reaction

ln A = ln Ao - kt

y = mx + c

slope = -k

and intercept = ln Ao
