Is this true or false? most of an atom's volume is the space in which electrons move.

Most of the volume of an atom is in an empty space in which negatively charged electrons move around the nucleus

The equilibrium constant for the reaction is 2.47

Explanation:

We are given:

Initial moles of ammonia gas = 29.0 moles

Equilibrium moles of nitrogen gas = 13.0 moles

Volume of the tank = 7.50 L

Molarity is calculated by using the formula:

The chemical equation for the decomposition of ammonia follows:

Initial:             3.87

At eqllm:       3.87-2x    x      3x

Evaluating the value of 'x'

So, equilibrium concentration of ammonia = (3.87 - 2x) = [3.87 - 2(0.577)] = 2.716 M

Equilibrium concentration of nitrogen gas = x = 0.577 M

The expression of for above equation follows:

Putting values in above equation, we get:

Hence, the equilibrium constant for the reaction is 2.47
