Calculate the time it takes for a reactant to reach 1% of its initial
mole content in a constant volume batch reactor if ra = -kca, k = 0.23 min-1.
plot the concentration profile, ca(t).
b) what assumptions were made in the application of the general mole balance equation for
the case of (a) the batch reactor, (b) cstr and (c) pfr?

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced. be sure your answer has the correct number of significant digits.
