Calculate the equilibrium constant, k, at 25°c for the galvanic cell reaction shown below: 8 h+(aq) + 5 fe2+(aq) + mno4-(aq) → mn2+(aq) + 5 fe3+(aq) + 4 h2o(l) e° = +0.74 v enter your answer in exponential format (sample 1.23e-4) with two decimal places and no units.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

catya that's not even a b or c

i think tornado but not 100%
