Having some confusion with this question....I have the answers, just not able to reach them. A flask of volume 5L is evacuated and 43.8 g of solid N2O4 is introduced at 77K. The sample is then warmed to 298K during which the N2O4 vaporizes and some dissociates to form brown NO...

X(g) + 2 Y(g) + 2 Z(g) -->3 M(g) + 2 N(g) I've already found the orders for the following to be: X is 2nd, Y is 1st, Z is 0 and overall of course is 3. But I am confused about the below question. I initially guess that No it doens't occur in one step..but the reason...

The hydrolysis of sucrose (C12H22O11) produces fructose and glucose (each C6H12O6). Two mechanisms are proposed: I) Step 1: C12H22O11 --> C6H12O6 + C6H10O5 (slow) Step 2: C6H10O5 + H2O--> C6H12O6 (fast) II) C12H22O11 + H2O--> C6H12O6 + C6H12O6 Would these mechanisms b...

For the first-order reaction A => 3 B + C, when [ A]0 = 0.014 mol·L-1, the concentration of B increases to 0.017 mol·L-1 in 2.7 min. (a) What is the rate constant for the reaction expressed as the rate of loss of A? I found this to be .1923, which I know is co...
