Styrene is polymerized using amide catalyst in liquid ammonia, anionically. How will the rate of reaction change, if the monomer concentration is doubled (keeping rest other things constant)?

Styrene is polymerized using amide catalyst in liquid ammonia, anionically. How will the rate of reaction change, if the monomer concentration is doubled (keeping rest other things constant)? Correct Answer quadrupled

According to the rate expression for overall rate Rp α 2 So the rate is quadrupled, if the monomer concentration is doubled.
