I am talking about the expression for the overall activation energy ,given by e=(e1k1+e2k2)/(k1+k2).

Well,I know that the activation energy of a parallel reaction can be determined by the arrhenius equation as (e1k1+e2k2)/(k1+k2) where e1,k1 and e2,k2 are the activation energies and rate constants for the two reacations.now consider the reaction A》B,and A》C since at every instant the reacted...

I've found this a very confusing thing:when we locate the second dark fringes above and below the central maxima,we divide the slit into four parts and claim that pairs of waves interfere destructively as the path difference would be wavelength/2.But what if we just divided it into two parts and...

many transition elements have variable oxidation state like Fe.what is the exact cause for this?they may not obey the octet rule,but what is the reason behind this?Also,elements like nitrogen are not transition elements and still show variable valency.what will be the electronic configuration of...

Velocity in this case(magnitude) is not constant.Therefore you have to differentiate velocity as a function of time this and find its value at the required time.However,since velocity increases uniformly and I've is linear,its derivative will be constant

The actual meaning of m/s2 is (m/s)/s.It is simplified for easy writing notation.As mentioned above,every quantity need not have a "physical" meaning.Force's unit is written as kg m2/s2.For this,we cannot write it as kg ((m/s)/s),this would just be non simplified and difficult to...

No,you cannot destroy gravity(gravitational force).But you can escape from the pull of the Earth towards its centre by traveling at the Earth's escape velocity(11.2 km/s) or greater. Then you will be orbiting the earth.That's the most you can do.

Is the amount of oxygen in the air always the same?if yes,how?or if not, how not?

What weight does our weighing machine show?Is it the mass or weight(mg)?

Thank You

If it has infinite resistance then how can electrons flow?

Thank you very much.

Can anyone give me the proof for fermat's little theorem?

I mean the flow of electrons,i.e without any medium,can electricity flow?

Does electricity travel through vacuum?If so ,is it a good conductor?What is its resistance.
