The rate constant of a chemical reaction increased from 0.100 s⁻¹ to 3.20 s⁻¹ upon raising the temperature from 25.0 °C to 55.0 °C. Calculate the value of (1/T1 - 1/T2) in Kelvin⁻¹, where T1 is the initial temperature and T2 is the final temperature.
A
0.0030 K⁻¹
B
0.0020 K⁻¹

D
0.0040 K⁻¹
Verified step by step guidance1
Convert the initial temperature (T1) from Celsius to Kelvin by adding 273.15 to 25.0 °C.
Convert the final temperature (T2) from Celsius to Kelvin by adding 273.15 to 55.0 °C.
Calculate the reciprocal of the initial temperature in Kelvin, which is 1/T1.
Calculate the reciprocal of the final temperature in Kelvin, which is 1/T2.
Subtract the reciprocal of the final temperature from the reciprocal of the initial temperature to find (1/T1 - 1/T2) in Kelvin⁻¹.
