    Would somebody please explain how my textbook has calculated the temperature at which below, the reaction of iron oxide with carbon is not feasible?

    I don't understand how and why 558.1/1000 becomes 1000/558.1.

    I have attached a picture of the equation shown in my book.

    Because dividing by a fraction is the same as multiplying by the fraction but upside down

    The T has been taken over to the other side to reverse the sign. The fraction is taken with it as it's multiplied and so to then get rid of it just to leave T you divide the other side by the fraction. Dividing by fractions means you flip it and times it by whatever you were dividing, if that makes sense
