At 100oC, the gaseous reaction A -> 2B + C is observed to be first order. On starting with pure A, it is found that at the end of 10 min, the total pressure of the system is 176.0 Torr, and after a long time, 270 Torr. From these data, find (a) the initial pressure of A; (b) the pressure of A at the end of 10 min; (c) the rate constant of the reaction [90.0; 43.0; 0.0647] The answers are in the bracket. Thank you!
