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

Options

  1. A2
  2. B0 25
  3. C0 5
  4. D1

Correct answer

D. 1

Step-by-step solution

1 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:
