MCAT Readiness Test

10 questions, balanced across the exam's topics. Answer each one, then submit for your practice readiness estimate and per-topic breakdown. This is a practice estimate — not a prediction or guarantee of your official exam result.

Question 1

Initial rates are measured for a reaction. Doubling [A] while holding [B] fixed quadruples the rate. Doubling [B] while holding [A] fixed doubles the rate. Which rate law fits these observations?

Rate = k[A][B] Rate = k[A]²[B]² Rate = k[A]²[B] Rate = k[A][B]²

Question 2

An ideal spring with k = 300 N/m is stretched 0.06 m from equilibrium. How much elastic energy is stored? Choose the closest value.

0.27 J 0.54 J 1.08 J 18 J

Question 3

A sealed ideal gas changes from 90 kPa, 4.0 L, and 300 K to 2.0 L and 330 K. What is its final pressure? Choose the closest value.

99 kPa 40.9091 kPa 198 kPa 180 kPa

Question 4

A net force does 12 J of work on a 2.0 kg object initially at rest. What is its final speed, assuming ordinary nonrelativistic motion?

Approximately 3.46 m/s 6.0 m/s 12 m/s Approximately 2.45 m/s

Question 5

The intensity of one sound is 10 times that of another. Using Δβ = 10 log10(I₂/I₁), what is the difference in sound intensity level? Choose the closest value.

20 dB 5 dB 10 dB 1 dB

Question 6

An ideal aqueous NaCl solution is 0.3 molal. Assume complete dissociation and Kf = 1.86 °C·kg/mol. By how many degrees Celsius is its freezing point depressed relative to pure water? Choose the closest value.

0.558 °C 1.116 °C 2.232 °C -1.116 °C

Question 7

In ideal electrolysis, M²⁺ + 2e⁻ → M. If charge 579000 C passes with 100% current efficiency, how many moles of metal are deposited? Use F = 96,500 C/mol electrons. Choose the closest value.

6 mol 0.3 mol 3 mol 12 mol

Question 8

A wire is replaced with one of the same material and temperature, 3 times as long and twice the radius. What is the new resistance divided by the original resistance? Choose the closest value.

1.33333 1.5 12 0.75

Question 9

An incompressible fluid flows steadily through a tube with no branches. The tube radius decreases from 4 mm to 2 mm. What happens to the mean flow speed?

It falls to one-fourth. It increases fourfold. It remains unchanged. It doubles.

Question 10

A reaction obeys rate = k[A]². When [A] is 0.1 M, its rate is 0.004 M/s. What is k? Choose the closest value.

0.8 M⁻¹·s⁻¹ 4e-05 M⁻¹·s⁻¹ 0.04 M⁻¹·s⁻¹ 0.4 M⁻¹·s⁻¹
