For the ideal gaseous reaction, the rate is generally expressed in terms of `(dP)/(dt)` instead of `(dC)/(dt)` or `(dn)/(dt)` (where C=`(n)/(V)` is concentration and n the no. of moles). What is the relation among these three expressions if T and V are constant?
A. `(dC)/(dt)=(dn)/(dt)=(dP)/(dt)`
B. `(dC)/(dt)=(1)/(V)(dn)/(dt)=(1)/(Rt)((dP)/(dt))`
C. `RT(dC)/(dt)=(dn)/(dt)=(dP)/(dt)`
D. None of these
