Consider the following reaction:

The reaction between CO and H₂ is carried out at a specific temperature with initial concentrations of CO = 0.31 M and H₂ = 0.46 M. At equilibrium, the concentration of CH₃OH is 0.14 M. Find the equilibrium constant at this temperature.

Explanation:

The ICE table is set up as shown in the image attached so that the individual concentration of species can be determined. The ICE table is required to keep track of changes in the concentrations of the various reactants in a system as the reaction progresses towards equilibrium position. I stands for initial concentration, C stands for change in concentration and E stands for concentration at equilibrium. See image attached for detailed solution.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
