WebIn chemical thermodynamics, an endergonic reaction (from Greek ἔνδον (endon) 'within', and ἔργον (ergon) 'work'; also called a heat absorbing nonspontaneous reaction or an unfavorable reaction) is a chemical reaction in which the standard change in free energy is positive, and an additional driving force is needed to perform this reaction. In layman's …
WebThe reaction rate law is known to be 2nd order, and for an initial concentration [NO2 (g)]o=0.0100M, the initial rate is 0.0350 M/s. Write the rate law, and give the value of the rate constant? A certain reaction follows zero-order kinetics. Suppose the reaction went to 50 % completion after 10 minutes.
