A chemical plant produces ammonia using the following reaction. What trade-off is made by running the reaction at a high temperature? 3H2 + N2 3 2NH3 + energy O A. The higher temperature increases the forward reaction rate, and the higher pressure increases the reaction rate.

B. The higher temperature decreases the reaction rate, but it also favors the forward reaction.

C. The higher temperature increases the reaction rate, but it also favors the reverse reaction.

D. The higher temperature decreases the forward reaction rate, and the pressure of the system is also lowered.​

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.

just took the test its not "d"
