The rate would be four times larger
The rate of reaction is directly proportional to the concentration of the reactant. Therefore, when the concentration doubles so should the rate. This is because there are more particles which are crowded close together, meaning they will collide more often (and more successfully) and therefore increasing the rate of reaction.
The rate of reaction is also decreased.

quadrupled

The rate would quadruple (increase by a factor of 4). This is because the rate depends on the SQUARE of the concentration of NO.
