Please help! Due tonight! Determine the reaction rate, with respect to nitrogen, for the reaction: N2(g) + 3H2(g) → 2NH3(g), between 10s and 50s, based on the following table:

answer;

18.5 seconds

explanation;

velocity is distance covered per unit time; it is given by displacement divided by time.

thus; time = displacement/velocity

total time = total displacement/velocity

total distance = 5000 meters south

total time = 5000/4.5

                  = 1111.11 seconds

but; 1 minute = 60 sec

thus; 1111.11 /60

                = 18.51 seconds

thus; the time taken is 18.5 seconds
