- Deduce the relation pv = nRT where R is a constant called universal.arrow_forwardGiven: A<--> B (ka & ka') B <--> C (kb& kb') so eq 1: d[A]/dt = -ka[A] + ka'[B] eq 2: d[B]/dt= ka[A] - ka'[B] - kb[B] + kb'[C] eq 3: d[C]/dt= kb[B] - kb'[C] Using steady state: ka[A] + kb'[C] = ka'[B] + kb[B] [B]= (ka[A] + kb'[C] ) / (ka' + kb) This can be inserted into equation 3 d[C]/dt = kb[B] - kb'[C] = kb((ka[A] + kb'[C] ) / (ka' + kb)) - kb'[C] Determine the k and k’, where the above mechanism is equivalent to the following: A ↔ C (k and k’) d[A]/dt= -k[A]+ k'[C] d[C]/dt= k[A] - k'[C] What is the simpilfied values of k & k'?arrow_forwardAsking for Q 9arrow_forward
