Suppose a 250. mL flask is filled with 1.4 mol of $NO_3$ and 0.60 mol of $NO_2$. The following reaction becomes possible: $NO_3(g) + NO(g) \rightleftharpoons 2NO_2(g)$ The equilibrium constant $K$ for this reaction is 6.83 at the temperature of the flask. Calculate the equilibrium molarity of $NO_2$. Round your answer to two decimal places.

Problem 2 [10 Marks] Assume that the input and output relation of the above RLC circuit can be represented as following complex domain representation: $E_o(s) = \frac{s+1}{s^2 + 4s + 4} E_i(s)$ 1) (6 marks) Calculate the system response $e_o(t)$ by using inverse Laplace transform when the system is subject to zero initial condition and a unit step input $e_i(t) = 1$ for $t>0$. Identify the transient and steady-state terms of the response in the system output response formulation you obtained; 2) (4 marks) Sketch the unit step response obtained from 1) and mark transient/dynamic and steady-state part of the system response respectively in the plot. 3) (3 marks) How about the system response $e_o(t)$ for a unit impulse input? (Optional: 3 bonus marks if you solve this sub-question).
