Plot the expected 1d mean squared displacement (in microns^2) for a particle 1 micron in diameter in oil with viscosity 5.6 cp at 25c using expression relating msd with particle diffusion coefficient. plot time on the x-axis between 0 - 10 seconds.

does the slope of the plot of mean squared displacement with time increase or decrease when viscosity decreases.

Which element is least likely to undergo a chemical reaction

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
