7.40 A sample of carbon dioxide (C*O_{2}) gas has a volume of 15,2 L at a pressure of 1.35 atm and a temperature of 33C. Determine the following for this gas sample . L a. Volume, in liters, at T = 42 degrees C and * V=10.L

Answer earth,water,fire and air;

Reaction involved in present system is :   c12h22o11 + h2o → 2 c6h12o6the reaction system is obeying following rate law:   rate = k[c12h22o11]thus, it is a first order reaction.now, for 1st order reactionrate constant (k) =  given: initial conc. = 3.0 g, final conc. = 2.7 g, t = 2.5 h∴rate constant (k) =  ∴ k = 0.04215 h-1now, for 1st order reaction, half life = 0.693/k = 0.693/0.04215 = 16.4 hthus correct answer is option b
