Answer» Solution :Consider a zero ORDER reaction `R to P` Rate `=K[R]^(0)` Rate=`K[R]^(0)` Rate = `K xx 1` where K - rate constant or velocity const Rate =- `d[R]//DT` `-d[R]//dt= k implies d[R]=-Kdt` `int d[R] =-Kint dt` `[R] = K+1` I-integration constant To find I, when t=0, [R] = [R_(0)]` `[R_(0)]=-K xx 0+1` `I=[R_(0)]` Substituting in EQ. (1) `[R]=Kt+[R_(0)]` `K=[R_(0)]-([R])/(t)` (b)
