1. Consider the reaction: N2 (g) + O2 (g)  2NO (g) + Cl2 (g) A reaction mixture at 400 C has the following composition: [NO] =
Olegator [25]

Answer:

The reaction is not at the equilibrium, we have more products than reactants.

Explanation:

Step 1: Data given

Temperature = 400 °C

When Q=K, this means the system is at equilibrium. There will not be a shift to either the left or the right.

When Q<K,it means we have more reactants than products. The system will, as reaction, make more products, this will cause the equilibrium to move to the right.

When Q>K,it means we have more products than reactants. The system will, as reaction, make less products and more reactants, this will cause the equilibrium to move to the left.

[NO] = 0.01 M

[N2] = 0.001 M

[O2] = 0.001 M

Kc = 0.0156

Step 2: The balanced equation

N2 (g) + O2 (g) ⇆ 2NO (g) + Cl2 (g)

Step 3: Calculate Q

Q = [NO]²/[N2][O2]

Q = 0.01²/(0.01*0.001)

Q = 10

Q>>Kc

This means we have more products than reactants. The system will, as reaction, make less products and more reactants, this will cause the equilibrium to move to the left.

The reaction is not at the equilibrium, we have more products than reactants.

Classify the following processes as exothermic or endothermic: (d) a person running;
Sonja [21]

The process releases energy and consequently we classify it as exothermic. (d) a person running releases warmness as muscle mass paintings. therefore, the procedure is exothermic.

d) Exothermic, heat is released as a person runs and muscle groups perform work.

A chemical response or bodily exchange is exothermic if warmth is released by using the system into the environment. Because the surroundings are gaining heat from the system, the temperature of the surroundings increases. The sign of q for an exothermic procedure is -ve due to the fact the device is dropping heat.

Some other examples of exothermic reactions:

1)Snow Formation in Clouds.

2)Burning of a Candle.

3)Rusting of Iron.

4)Formation of Ion Pairs.

5)response of strong Acid and Water. etc...
