Question 1: The balanced equation below is a reversible reaction. The concentration of each chemical species was
measured at various time points.
N2(g)+3 H2 (g) <—> 2NH3 (g)

a) When was equilibrium reached?
b) Write the equilibrium expression.
c) Would you expect the Keg to be greater than or less than 1? Justify your answer using data from the graph.

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:
