The answer is B. You are correct.
Answer: 1.037M
Explanation:
Since the rate constant unit is per seconds, therefore it is a first order reaction.
First order reaction equation is given as
InA= -kt +InAo
Where,Ao is the initial concentration of reactant =0.600M
A is the concentration of reactant at a specifies time t=3×60=180s
and k is the rate constant
InA = -6.50×10^-3 ×180 +In(0.6)
InA = -1.17 + 0.5108
InA= -1.680
A = e-1.680
A= 1.037M
Therefore the concentration after 3minutes is 1.037M
Option D. maintain their positions.
Pressure does not modify the relative position of the atoms in solid matter. The atoms are kept in position by the atomic and molecular bonds whose length is a feature of every pair of atoms.
For example, all the bonds of C-C and C-H in the wood will have the same bond length
Flat as more oxygen and water can react over it think of it like this would a cube rust faster than a sheet
