Question

How many moles of gaseous oxygen at one atmosphere is considered for the reaction with element for plotting a graph in Ellingham diagram?

Options

• 0.5

• 2

• 1

• 0.25

Answer 1

1

Explanation:

The standard free energy change (6G0 ) per 1 mole of oxygen is represented on the y-axis, while temperature (K) is plotted on the x-axis in the Ellingham diagram graph. For the Ellingham diagram, one mole of gaseous oxygen at one atmosphere is used to create a graph for the reaction with element. The following is an example:
