Consider the following equilibrium: (T2-LG6) N_2O_4(g) + energy 2 NO_2 (g) Which of the following shows the relationship between concentration and time as a result of adding a catalyst at time t = 1?
Expert Answer
Answer
29) The exact relaton betweeen concentration and time is represented by the graph ‘D’
Since the reaction is at equilibrium, rate of forward reaction is equal to rate of backward reaction and at equilibrium, the concentration of reactant and product maintains a constancy. When a catalyst is added, it enhances the rate of forward as well as backward reaction to the same extent, and hence equiliobroum remains unaltered.
