Be sure to answer all parts. By what factor does the fraction of collisions with energy equal to or greater than activation energy of 100. kJ/mol change if the temperature increases from 34.0°C to 52.0°C? Give your answer in scientific notation.

Factor = 8.77

Explanation:

Fraction of collision with energy greater than or equal to the activation energy  can be given by the formula:

R = 8.314 J/mol.K

When Temperature = 34⁰C = 34 + 273 = 307 K

When Temperature =  52⁰C = 52 + 273 = 325 K

Factor = 8.77

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
