Final answer:
The rate constant (k) represents the speed at which a chemical reaction occurs. It is determined by the Arrhenius equation, which relates the rate constant to the temperature, activation energy, and the frequency factor.
Step-by-step explanation:
The rate constant (k) represents the speed at which a chemical reaction occurs. It is determined by the Arrhenius equation, which relates the rate constant to the temperature, activation energy, and the frequency factor. The equation for the rate constant is:
k = Ae-Ea/RT
Where:
- k is the rate constant
- A is the frequency factor
- Ea is the activation energy
- R is the gas constant
- T is the temperature in Kelvin
To calculate the value of the rate constant at 225°C, you would need to know the values of A, Ea, R, and T.
