(a)
Interpretation:
The effect of hot sunny day on nitrogen dioxide concentration is to be stated.
Concept introduction:
Equilibrium reaction is a
(b)
Interpretation:
The effect of cool day on nitrogen dioxide concentration is to be stated.
Concept introduction:
Equilibrium reaction is a reaction where, the rate of forward reaction is equal to the backward reaction. According to Le Chatelier’s Principle, if equilibrium is disturbed by changing the conditions like temperature, pressure or concentration, the equilibrium of the reaction shifts in the direction to counteract the change.

EBK INTRODUCTORY CHEMISTRY
- Suppose a reaction has the equilibrium constant K = 1.3 108. What does the magnitude of this constant tell you about the relative concentrations of products and reactants that will be present once equilibrium is reached? Is this reaction likely to be a good source of the products?arrow_forwardWhat is Le Chteliers principle? Consider the reaction 2NOCI(g)2NO(g)+Cl2(g) If this reaction is at equilibrium. what happens when the following changes occur? a. NOCI(g) is added. b. NO(g) is added. c. NOCI(g) is removed. d. Cl2(g) is removed. e. The container volume is decreased. For each of these changes, what happens to the value of K for the reaction as equilibrium is reached again? Give an example of a reaction for which the addition or removal of one of the reactants or products has no effect on the equilibrium position. In general, how will the equilibrium position of a gas-phase reaction be affected if the volume of the reaction vessel changes? Are there reactions that will not have their equilibria shifted by a change in volume? Explain. Why does changing the pressure in a rigid container by adding an inert gas not shift the equilibrium position for a gas-phase reaction?arrow_forwardAt room temperature, the equilibrium constant Kc for the reaction 2 NO(g) ⇌ N2(g) + O2(g) is 1.4 × 1030. Is this reaction product-favored or reactant-favored? Explain your answer. In the atmosphere at room temperature the concentration of N2 is 0.33 mol/L, and the concentration of O2 is about 25% of that value. Calculate the equilibrium concentration of NO in the atmosphere produced by the reaction of N2 and O2. How does this affect your answer to Question 11?arrow_forward

(There may be more than one answer.) a. the initial concentrations of the reactants b. the initial concentrations of the products c. the temperature of the system d. the nature of the reactants and products Explain.arrow_forwardThe atmosphere consists of about 80% N2 and 20% O2, yet there are many oxides of nitrogen that are stable and can be isolated in the laboratory. (a) Is the atmosphere at chemical equilibrium with respect to forming NO? (b) If not, why doesnt NO form? If so, how is it that NO can be made and kept in the laboratory for long periods?arrow_forwardConsider the following hypothetical dissociation: AB3(s) A3+(aq)+3 B(aq)H0What effect will each of the following have on the position of equilibrium? (a) addition of A(NO3)3 (b) increase in temperature (c) adding Na+, forming NaBarrow_forward
