WebA chemical reaction occurs when you no longer have the same substance or substances, but have some new substance or substances. Changing the state (such as boiling, freezing, melting, or grinding up) still leaves you … WebThus, the heat given off or absorbed during a chemical reaction at constant pressure is equal to the change in the enthalpy of the system. H = q p (at constant pressure) The relationship between the change in the internal energy of the system during a chemical reaction and the enthalpy of reaction can be summarized as follows. 1. WebThe equilibrium of the reaction is determined by the final energy states of S and P, which are unaffected by enzymatic catalysis. In order for the reaction to proceed, however, the substrate must first be converted to a higher energy state, called the transition state. toxin producing fungi
