Akinetics experiment is set up to collect the gas that is generated when a sample of chalk, consisting primarily of solid caco3, is added to a solution of ethanoic acid, ch cooh. the rate of reaction between caco, and ch3cooh is determined by measuring the volume of gas generated at 25°c and i atm as a function of time. which of the following experimental conditions is most likely to increase the rate of gas production?

(a) decreasing the volume of ethanoic acid solution used in the experiment acid solution used in the experiment experiment is performed
(b) decreasing the concentration of the ethanoic
(c) decreasing the temperature at which the
(d) decreasing the particle size of the caco, by grinding it into a fine powder

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.
