Concentration and How It Affects The Rate of Reaction
When two reactants are in the same fluid phase, their particles collide more frequently than when one or both reactants are solids (or when they are in different fluids that do not mix). If the reactants are uniformly dispersed in a single homogeneous solution, then the number of collisions per unit time depends on concentration and temperature, as we have just seen. If the reaction is heterogeneous, however, the reactants are in two different phases, and collisions between the reactants can occur only at interfaces between phases. The number of collisions between reactants per unit time is substantially reduced relative to the homogeneous case, and, hence, so is the reaction rate. The reaction rate of a heterogeneous reaction depends on the surface area of the more condensed phase.
concentration clearly affects the rate of reaction.
However, more yeast are damaged in dough frozen at a fast freezing rate, resulting in greater cell death; therefore, more glutathione is released, which affects the gluten network by reducing S-S to sulfhydryl groups (-SH) and decreasing the amount of gas retention. shows the effect of the trehalose concentration and storage time on CO2 production.
