Answer : The rate constant at 785.0 K is,
Explanation :
According to the Arrhenius equation,
or,
where,
= rate constant at
=
= rate constant at
= ?
= activation energy for the reaction = 262 kJ/mole = 262000 J/mole
R = gas constant = 8.314 J/mole.K
= initial temperature =
= final temperature =
Now put all the given values in this formula, we get:
Therefore, the rate constant at 785.0 K is,
The question is incomplete. The complete question is :
Hydrogen is manufactured on an industrial scale by this sequence of reactions:
The net reaction is :
Write an equation that gives the overall equilibrium constant in terms of the equilibrium constants
and
. If you need to include any physical constants, be sure you use their standard symbols, which you'll find in the ALEKS Calculator.
Solution :
...............(1)
...................(2)
On multiplication of equation (1) and (2), we get
.................(4)
Comparing equation (3) and equation (4), we get
