Answer 2

Effect of Temperature Increase on Reaction Rate

When the temperature increases by 20 degrees Celsius, the reaction rate will increase. The relationship between temperature and reaction rate is described by the Arrhenius equation, which states that for every 10-degree Celsius increase in temperature, the reaction rate approximately doubles.

The general form of the Arrhenius equation is:

k = A * e^(-Ea/RT)

Where: - k is the rate constant - A is the pre-exponential factor - e is the base of the natural logarithm - Ea is the activation energy - R is the gas constant - T is the temperature in Kelvin

When the temperature increases, the value of T in the Arrhenius equation increases, leading to a higher rate constant k and, consequently, a faster reaction rate.

The specific relationship between temperature and reaction rate can be calculated using the Arrhenius equation and the given activation energy and pre-exponential factor for the reaction.

Calculation

Given that the coefficient is 4 and the temperature increases by 20 degrees Celsius, we can calculate the new reaction rate using the Arrhenius equation. However, without the specific values of the activation energy and pre-exponential factor, a precise calculation cannot be provided.

To calculate the new reaction rate, we would need the specific values of the activation energy and pre-exponential factor for the reaction in question. Once these values are known, the new reaction rate can be calculated using the Arrhenius equation with the increased temperature.

Conclusion

In conclusion, an increase in temperature by 20 degrees Celsius will lead to a higher reaction rate, as described by the Arrhenius equation. The specific impact on the reaction rate can be calculated using the equation with the given activation energy and pre-exponential factor for the reaction.
