solve it in a clear way, please

A chemical reaction AB is carried out in a closed vessel. The following data are taken for the concentration of A,CA(g/L), as a function of time, t(min), from the start of the reaction: A proposed reaction mechanism predicts that CA and t should be related by the expression lnCA0CAcCACAc=kt where k is the reaction rate constant. (a) Do the data support this prediction? If so, determine the value of k. (b) If the tank volume is 30.5 gallons and there is no B in the tank at t=0, how much B(g) does the tank contain after two hours
