Answer:
Rate constant at 725 K is 
Explanation:
According to Arrhenius equation for a reaction-
where 
and 
are rate constants of reaction at 
and 
temperatures (in kelvin) respectively.
is activation energy of reaction.
Here = 600 K , = 
= 725 K, = 262 kJ/mol and R = 8.314 J/(mol.K)
So plugin all the values in the above equation-
So, =
Hence rate constant at 725 K is
Answer:
Is an exemplar of Italian Renaissance painting.
Explanation:
