help please?

Question

2 MnO4- (aq) + 5 HNO2 (aq) + H+ (aq)→ 2 Mn2+ (aq) + 5 NO3- (aq) + 3 H2O (l) 

Calculate the rate (in M s-1 ) at which the HNO2 concentration is decreasing if the MnO4- is decreasing at a rate of 0.024 M s-1 .

Answer 1

(0.024 M/s MnO4{-}) x (5 mol HNO2 / 2 mol MnO4{2-}) = 0.060 M/s HNO2

Answer 2
