For the first-order reaction, 2 N2O(g) → 2
N2(g) + O2(g), what is the
concentration of N2O after 3 half-lives if 0.15 mol...

Urea decomposes as a first order in respect to urea and as a
first order overall reaction. The decomposition of urea in a 0.16M
HCl occurs according to:
NH2CONH2
(aq) + H+ (aq)
+ 2 H2O
(l)
2 NH4+ (aq) + HCO3-
(aq)
When [NH2CONH2] = 0.250 M, the rate at
60.5°C is 8.45 × 10-5 M/s.
What is the rate constant? What is the concentration of urea in
this solution after 5.00 × 103 sec?
What is the...

The rate constant of a first-order reaction is 0.0032 x
10-4 L/mol *s at 640 K. If the activation energy is
176,406J/mol, calculate the temperature at which is rate constant
is 0.0039 x10 -4 L/mol*s.
Show your work please.

A gas-phase decomposition is first-order with respect to the
reactant, R. If the initial concentration of R is 1.0 ´

Consider the reaction which is third order overall but first
order in each of three concentrations. If the concentration of two
of the species are very large compared to that of the third, with
what functional form will the concentration of the third species
decrease in time?

The decomposition of A to B is a first-order reaction with a
half-life of 85.9 min when the initial concentration of A is 0.483
M: A → 2B How long will it take for this initial concentration of A
to decrease by 23.0%? PLEASE HURRY I DONT HAVE MUCH TIME TO ANSWER

Consider the CSTR with first order reaction and the process
parameters and variables are given by: The process parameters and
variables are defined as: CA0 = feed concentration = 2.7 mol/L. Cp
= heat capacity of the reactor feed and product (1000 cal/kg*K) =
Cv. E/R = normalized activation energy (20,000 K). F = mass feed
rate and product rate (10 kg/s). k0 = rate constant (1.97×10^24
1/s). Q = heat addition rate (initially 700,000 cal/s). T0 = feed
temperature...
