Does anyone know how to convert 72° f to °c in chemistry

To find Celsius from Fahrenheit, you subtract 32 and divide that by 1.8
72-32=40/1.8=22.2222...
So about 22.2 degrees Celsius.

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.
