All of the following are true of standard cell potentials EXCEPT: (Select all that apply.) Select all that apply: A galvanic cell generates electric current spontaneously only if the cell potential is positive. The anode is the species with the greater standard reduction potential. Standard cell potential is dependent on the stoichiometry of the overall reaction. A galvanic cell generates electric current spontaneously only if the cell potential is negative.

Nitric oxide (no) can be formed from nitrogen, hydrogen and oxygen in two steps. in the first step, nitrogen and hydrogen react to form ammonia: n2(g) + 2 h_2(g) rightarrow 2 nh_3 (g) delta h = -92. kj in the second step, ammonia and oxygen react to form nitric oxide and water: 4 nh_3(g) + 5 o_2(g) rightarrow 4no(g) + 6 h_2o(g) delta h = -905. kj calculate the net change in enthalpy for the formation of one mole of nitric oxide from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
