Question

Consider the following thermochemical data
M +1/2 O2 -----> MO ΔG° = – 100 kJ
N +1/2 O2 -----> NO ΔG° = – 200 kJ
P +1/2 O2 -----> PO ΔG° = – 300 kJ

where M, N, P represent different metals.
Select the correct statement
A. N can act as reducing agent for both MO and PO


B. M can act as reducing agent for both NO and PO


C. P can act as reducing agent for both NO and MO


D. N can act as reducing agent for PO but not for MO

Answer 1

Answer:

c)p can act as a reducing agent for both NO and MO

Explanation:

Delta G represents Gibbs free energy which explains the spontaneity of the reaction ,more negative value more spontaneous the reaction is ,that means is the desire for happing of reaction is more

if we observe the question we see the third reaction has more negative value of Delta G so P gets oxidized more spontaneously so it reduces others more spontaneously
