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?

Options

A. `(dC)/(dt)=(dn)/(dt)=V/(RT)(dP)/(dt)`
B. `(dC)/(dt)=1/V(dn)/(dt)=1/(RT)(dP)/(dt)`
C. `(dP)/(dt)=(dn)/(dt)=(dc)/(dt)`
D. none of these

Answer

B
