If the concentration of B is doubled while the concentration of A is unchanged, the rate will ________. A (g) + 3B (g) → C (g) + 2D (g)
Rate = k[A][B]3

Question

According to the given rate law, the rate of the reaction is directly proportional to the concentration of B raised to the power of 3. Therefore, if the concentration of B is doubled, the rate will increase by a factor of 2^3 = 8. So the correct option is D, the rate will be increased by a factor of 8.

If the Concentration of B Is Doubled While the Concentration
