18.67 Consider the reaction Given that DG8 for the reaction at 258C is 173.4 kJ/mol, (a) calculate the standard free energy of formation of NO, and (b) calculate KP of the reaction. (c) One of the starting substances in smog formation is NO. Assuming that the temperature in a running automobile engine is 11008C, estimate KP for the above reaction. (d) As farmers know, lightning helps to produce a better crop. Why

a. 86.7KJ/mol

b. 2.5 * 10^30

c. 1.42 * 10^55

d. Lightning produces more amount of NO from nitrogen and oxygen thus giving a better crop as NO is essential for crop growth

Explanation:

Complete question is as follows;

Consider the reaction N2(g)+ O2(g) —-> 2NO(g)

Given that ΔG0 for the reaction at 25 degrees celsius is 173.4 kJ/mol a) calculate the standard freeenergy of formation of NO and B) calculate KP ofthe reaction. C) One of the starting substances in smog formationis NO. Assuming that the temperature in a running automobile engine is 1100 degreesC, estimate KP of the above reaction.D) As farmers know, lighting helps to produce a better crop.Why?
