Question: General mole balance equation of species ‘i’ at any instant is as follows: ________

Options

A : Rate of moles of ‘i’ in = Rate of moles of ‘i’ out

B : Rate of moles of ‘i’ in + Rate of moles of ‘i’ out = Rate of moles of ‘i’ accumulated

C : Rate of moles of ‘i’ in + Rate of moles of ‘i’ accumulated = Rate of moles ‘i’ out

D : Rate of moles of ‘i’ in – Rate of moles of ‘i’ consumed by reaction – Rate of moles of ‘i’ out = Rate of moles of ‘i’ accumulated
