The false positive from the response of hydrogen peroxide and the immunizing circle would be created by poor specificity. The recipe for specificity is TN/TN+FP. False-positive outcomes can be ascribed to meddling substances in nature where the strips are put away or utilized, for example, hydrogen peroxide (H2O2) or fade (hypochlorite).

The E_{a} for the process is 7265.2 Joules/mol.

<h3>Calculation of E_{a} :</h3>

Instead of providing us with the rate constants at two distinct temperatures, the information in the issue provides us with the time needed at two different temperatures.

For a specific process, the ratio of rate constants will match the ratio of rates.

A ratio of rates will have an inverse relationship with a ratio of times since rates are inversely related to time (greater time equals smaller rate). Below is a summary of this.

Using Arrhenius equation:

ln\frac{k_{1} }{k_{2} } =\frac{-Ea [1/T_{2} -1/T_{1}] }{R}

k_{1} =1/4.5

k_{2} =1/4.8

T_{1} = 273 +100

= 373 K

T_{2} = 273 + 90

= 363 K

Gas constant R = 8.314 Joules/Kelvin.mol

ln4.8/4.5 = -Ea/8.314 [1/373 - 1/363]

0.064539 x 8.314 = Ea x 0.000073856

E_{a} = 7265.2 Joules/mol

Hence, The E_{a} for the process is 7265.2 Joules/mol.
