Determine ΔrG° for the following reaction:

Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)

Use the following reactions with known ΔrG° values:

2Fe(s)+32O2(g)→Fe2O3(s), ΔrG° = - 742.2 kJmol−1

CO(g)+12O2(g)→CO2(g), ΔrG°= - 257.2 kJmol−1

Express your answer using one decimal place.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >
