At room temperature (20), milk turns sour in about 63 hours. In a refrigerator at 3, milk can be stored three times as long before it sours.
Estimate the activation energy of the reaction that causes the souring of milk.
A gas sample was collected over water at 25.3 degrees Celsius, The total pressure is determined to be 0.97 atm. What is the partial pressure of the gas that was collected?
Determine the pressure (in atm) inside the can if a metal can of 1.00 qt contains 0.150 grams of Helium at a temperature of 20 degrees Celsius also explain Is this pressure greater or less than standard atmospheric pressure?
A quantity of Oxygen (g is originally at 4.75 atm and 26 degree Celsius in a 5.00 Litre container is transferred into the same container determine the total pressure in the new container?
A gas originally at 27 degrees celsius and 1.00 atm pressure in a 3.9 L flask is cooled at constant pressure until the temperature is 11 degrees celsius. determine the new volume of the gas and express your answer in Litre.
A certain reaction has an activation energy of 70.0 Kj/mol and a frequency factor of A1 = 4.80×1012. A) What is the rate constant, k , of this reaction at 30.0 C
Explain different moderators used in nuclear reactors
Calculate the amount of energy needed in calories to heat 145 g of water from 22.3 degrees celsius to 75.0 degrees celsius. (water in j/g degree celsius = 4.184, cal/ g degree celsius = 1)
a) when 34.0g of NH3 reacts with 96.0g of O2 what is the partial pressure of NO in the sealed container?
If someone can go in depth into finding the Ka to this and then guiding me through the rest of the steps, I'd be eternally grateful
