The activation energy for the isomerization of cyclopropane to propene is 274 kJ/mol. By what factor does the rate of this reaction increase as the temperature rises from 257 to 280 degree C? The factor is the ratio of the rates. Since rate is directly proportional to rate constant, the factor is also ratio of rate constants Make sure your units are correct and cancel properly and use the correct expression: k= Ae^-E_a/RT A catalyst decreases the activation energy of...
A decomposition reaction has a half-life that is directly proportional to the initial concentration of the reactant. What is the order of the reaction? Geologists can estimate the age of rocks by their uranium-238 content. The uranium is incorporated in the rock as it hardens and then decays with first-order kinetics and a half-life of 4.5 billion years. A rock is found to contain 83.4% of the amount of uranium-238 that it contained when it was formed. (The amount that...
o Consider the renction 2A(g) + B(g) + 2(g) 2D(8) E(s) Suppose at time =0, the partial pressures of the reactant gases are 5 atm A, 10 atm B, and 8 atm C. After 20 minutes the partial pressure of A was found to be 1 atm. a) What is the initial total pressure in the flask at time=0? Bus P + P +++ b) What is the total pressure inside the flask after 20 minutes? Set up a start,...
