1) Establishing the doubt

i) Doubt for ln(k)

Eg: ln(k)= 0. 26136

Uncertainty= ((0. 05)/ (0. 26136))100

Uncertainty=> +/- 6%

ii) Doubt for 1/T

Eg: 1/T= 0. 003309

Uncertainty= (0. 000001/ 0. 003309)100

Uncertainty=> 0. 0034%

Graph:

1) Determining the activation energy of a light stick

i) In order to find the activation strength, we must discover the incline

Slope= -23616 K

ii) Now connect the ideals into the formula below

Ea= (-R)(slope)

Exactly where Ea is a activation strength, R is a rate constant (8. 314 J/mol*K)

Ea= -8. 314 (-23616)

Ea= 196343. 6 J/mol

Ea= 196. 3 kJ/mol

Ea= 196 kJ/mol +/- zero. 51%

iii) Calculating the utmost and lowest values

Optimum: 188 kJ/mol

Lowest: 173 kJ/mol

2) Identifying the percent error

Assumptive value: 195 kJ/mol
