For the reaction IO_3^- (aq) + 5I^- (aq) + 6H^+ (aq) rightarrow 31_2 (aq) + 3H_2

Question

For the reaction IO_3^- (aq) + 5I^- (aq) + 6H^+ (aq) rightarrow 31_2 (aq) + 3H_2 O (l) the rate of disappearance of IO^-_3 (aq) at a particular time and concentration is 2.9 Times 10^-3 mol/(L middot s) What is the rate of appearance of I_2 (aq) ? -8.7 Times 10^3 mol/(L middot s) 2.9 Times 10^-3 mol/(L middot s) For the hypothetical reaction A + 2B rightarrow 2C + D, the initial rate of disappearance of A 2.0 Times 10^-2 mol/(L middot s) What is the initial rate of disappearance of B? 1.4 Times 10^- mol/(L middot s) 4.0 Times 10^-4 mol/(L middot s)

Explanation / Answer

1. If rate of disappearence of IO3- = 2.9 x 10^-3 mol/L.s

rate of appearence of I2 = 3 x 2.9 x 10^-3 = 8.7 x 10^-3 mol/L.s

Answer : C) 8.7 x 10^-3 mol/L.s

2. If rate of disappearence of A = 2 x 10^-2 mol/L.s

rate of disappearence of B = 2 x 2 x 10^-2 = 4 x 10^-2 mol/L.s

Answer : E) 4.0 x 10^-2 mol/L.s
