Chemical reaction kinetics

Chemical reaction kinetics

Chemical reaction kinetics

(OP)
Can someone give me an idea on how to solve this:

two reactions take place in constant temperature, constant volume vessel:

reaction 1: A >> B+C

reaction 2: 2C <=> D    for this reaction Kp = 4bar^(-1)

Determine the reaction rate constant of reaction 1. Only A is present at the start.

       t[min]                     Ptot[mbar]
       0                          1000
       30                         1129
       60                         1222
       90                         1296
       120                        1356
       150                        1405
       180                        1446


Thankyou very much

RE: Chemical reaction kinetics

Sounds like a homework problem to me.
In any case, you can, by using algebra, solve for one of the partial pressures of one of the components (e.g. C).  Then by molar balance solve for all the other components at any given time of the reaction.  I assume the rate equation would be based on A and is probably first order.  A log plot of A partial pressure versus time would show rate constant.
