The existence of each reaction as a redox or not is to be determined. In case of redox reaction, oxidized and reduced substances are to be identified. Concept Introduction: Oxidation is defined as the addition of oxygen or loss of electrons. A substance which undergoes oxidation is said to be oxidized. The substance which is oxidized is called as reducing agent. Reduction is defined as the addition of hydrogen or gain of electrons. A substance which undergoes reduction is said to be reduced. The substance which is reduced is known as oxidizing agent. Reaction that involves both oxidation and reduction simultaneously is known as redox reaction. For each element, oxidation number is based on the number of electrons assigned to it.

Using reaction free energy to predict equilibrium composition Consider the following equilibrium: 2NOCI (g) 2NO (g) + Cl2 (g) AGº =41. kJ Now suppose a reaction vessel is filled with 4.50 atm of nitrosyl chloride (NOCI) and 6.38 atm of chlorine (C12) at 212. °C. Answer the following questions about this system: ? rise Under these conditions, will the pressure of NOCI tend to rise or fall? x10 fall Is it possible to reverse this tendency by adding NO? In other words, if you said the pressure of NOCI will tend to rise, can that be changed to a tendency to fall by adding NO? Similarly, if you said the pressure of NOCI will tend to fall, can that be changed to a tendency to rise by adding NO? yes no If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO needed to reverse it. Round your answer to 2 significant digits. 0.035 atm ✓ G 00. 18 Ar
