Answer:
0.314 s⁻¹
Step-by-step explanation:
Use the <em>Arrhenius equation.</em>
Data:
k₁ = 0.0275 s⁻¹; k₂ = ?
Eₐ = 75.5 kJ·mol⁻¹
T₁ = 20 °C = 293.15 K; T₂ = 45°C = 318.15 K
<em>Calculation: </em>
k₂ = 0.0275 × 11.41
k₂ = 0.314 s⁻¹

Answer:
Initial temperature, T1 = 15°C
Explanation:
Given the following data;
Initial volume, V1 = 250 mL to Liters = 250/1000 = 0.25 L
Final temperature, T2 = 30°C
Final volume, V2 = 0.5 L
To find the initial temperature T1, we would use Charles' law.
Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Charles is given by;
Making T1 the subject of formula, we have;
Substituting into the formula, we have;
<em>Initial temperature, T1 = 15°C</em>
