In the Haber process shown above, which combination of conditions would maximize the yield of ammonia while considering both equilibrium position and reaction rate?

A High temperature (500°C) and high pressure (200 atm) with iron catalyst B Moderate temperature (450°C) and high pressure (200 atm) with iron catalyst C Low temperature (200°C) and high pressure (200 atm) without catalyst D High temperature (700°C) and low pressure (50 atm) with iron catalyst

Question 2 / 10

Wave Properties ⭐⭐ Medium 3 points

A wave travels through a medium with the properties shown above. If the wave frequency is 150 Hz, what happens to the wavelength and wave speed when the wave enters a denser medium where its frequency remains constant?

A Wavelength increases, wave speed increases B Wavelength decreases, wave speed decreases C Wavelength increases, wave speed decreases D Wavelength decreases, wave speed increases

Question 3 / 10

A 5 kg box rests on a 30° incline with a coefficient of friction μ = 0.2. What is the acceleration of the box down the incline? (Use g = 10 m/s²)

A 1.5 m/s² down the incline B 3.3 m/s² down the incline C 5.0 m/s² down the incline D The box remains stationary

Question 9 / 10

Organic Chemistry ⭐⭐ Medium 3 points
