the value of the rate constant at 302 degrees Celsius is 2.45 x 10^-4 L/mol s and at 508 degrees celsius the rate constant is 0.624 L/mol s. the value of R is 8.3145 J/K mol. Calculate the value of the rate constant for this reaction at 375 degrees celsius. I already calculated the activation energy which is 140.3 kj.
For each of the following, calculate the concentration of Tris, Tris-H+ and the pH of the solution in each of the following solutions.
The zinc content of a 1.23 g ore sample was determined by dissolving the ore in HCl, which reacts with the zinc, and then neutralizing excess HCl with NaOH. Zn+2HCl-->ZnCl2+H2
An experiment shows that a 112-mL gas sample has a mass of 0.120 g at a pressure of 733 mmHg and a temperature of 33.0°C.
How much heat is released when 4.50 g of methane gas is burned CH4 (g) + 2O2(g) -> CO2 (g) + 2H2O(l) H=-890kJ
How much forested land would be needed to produce all of the given country's power? (Assume that the given country has little fossil resources.) Is this a sustainable alternative?
Write a chemical equation describing the condensation process for CO2 and a chemical equation describing the freezing
The annual production of sulfur dioxide from burning coal and fossil fuels, auto exhaust and other resources is about 26 million tons. the equation for the reaction is S + O2= SO2.
Metal A was determined to be 95% extracted into methylene chloride with dethizone at pH6, when equal volumes of aqueous and non-aqueous solvents were used. what is the distribution ratio of A
What volume of 0.160 M of Li2S solution is required to completely react with 125 mL of 0.160 M of Co(NO3)2
"Crossed" or "mixed" aldol condensations are practical for synthesis, if one of the aldehydes (or ketones) has no alpha-hydrogen atoms. Explain.
What volume of oxygen is required to burn completely 401 cm3 (centimeters cubed) of butane, C4H10 (All substances are gases measured at the same temperature and pressure.)
What mass of solid sodium formate (of MW 68.01)must be added to 115 mL of 0.57 mol/L formic acid (HCOOH) to make a buffer solution having a pH of 4.16? Ka = 0.00018 for HCOOH.
