Answer:
1) first order
2) second order
3) zero order
Explanation:
The curve of a first order reaction shows it to be exponential. In fact for a first order reaction, the concentration at a time t is an exponential function;
[A]t= [Ao] e^-kt
Where
[A]t = concentration at time =t
[Ao]= initial concentration
k= rate constant
t= time
For a second order reaction, the rate of reaction is directly proportional to the concentration of reactants.
For zero order reactions, rate of reaction is independent of concentration hence rate = k(rate constant)
The relative mass of an electron is 1/1840 the mass of a C-12 atom. Hence, option B is correct.
<h3>What is an electron?</h3>
An electron is a negatively charged subatomic particle.
An electron is very small, about 1/1,837th the mass of a proton. Atomic Weights Atomic mass of an atom is expressed in atomic mass units (amu) which are approximately grams. A more conventional way of expressing the mass of an atom is Atomic Weight.
Atomic mass units are expressed relative to the atomic mass unit of an unbound neutral carbon-12 atom.
Hence, the relative mass of an electron is 1/1840 the mass of a C-12 atom.
