Final answer:
The statement is false; the reaction rate is influenced by factors like temperature, reactant concentration, and presence of enzymes, but not directly by mean reaction time.
Step-by-step explanation:
The statement that transmission rate can be increased by decreasing the mean reaction time is false. The transmission rate, in the context of reaction rates in chemistry, is generally not affected directly by mean reaction time. However, factors such as temperature, concentration of reactants, and surface area do influence how fast a reaction proceeds.
For instance, increasing temperature typically increases the reaction rate because it raises the energy of the molecules involved, leading to more frequent and productive collisions. Conversely, as the reaction proceeds and the concentration of reactants decreases, as indicated for a second-order reaction, the half-life increases and the reaction rate decreases. This concept is supported by information showing that the reaction rate slows down as the concentration of reactants decreases over time (t = 200-300 h), and that the half-life of a second-order reaction increases as the reactant concentration decreases.
The presence of enzyme also affects the reaction rate; increasing the amount of enzyme can increase the rate, provided that there is sufficient substrate available, demonstrating that reaction rates are dependent on the conditions and makeup of the reaction system rather than the mean reaction time.
