A reaction is in zero order kinetics when the reaction rate depends only on enzyme concentration.
<h3>What do we mean by chemical kinetics?</h3>
Understanding the speeds of chemical reactions is the focus of the physical chemistry field of chemical kinetics, commonly referred to as reaction kinetics. Thermodynamics, in contrast, deals with the direction in which a process happens but does not, by itself, reveal the pace at which it occurs. Chemical kinetics comprises studies of how experimental circumstances affect a chemical reaction's rate and reveal details about the reaction's mechanism and transition phases, as well as the creation of mathematical models that can also characterize a chemical reaction's features.
Explanation: Heat flows from high to low. After you convert the Celsius into kelvin the Zn pellet has 323K and the water has 301K which results the transfer of the heat energy of the pallet to the water. ( you don’t have to convert, but it just make it easier) hope this helped you :)
