Question

2 A + 3 B Right arrow 4 C + 5 D In the first 120 s of the given reaction, 0.500 moles of B disappear. In that time period, what is the rate of appearance of C in mol/min?

Answer 1

2 A + 3 B Right arrow 4 C + 5 D In the first 120 s of the So number of moles C = 0.5 mole B ( 4 mole c / 3 moles B) Number of moles C = 0.67 moles C appeared in 120 s So mol/min = 0.67 moles / 2 min = 0.33 moles C / min
