Why are `F_0 - F_1` particles complexes that catalyse the redox reactions when energy flows down the energy gradient from NADH to `O_2`?

Name the four protein complexes that catalyse the redox reactions when energy flows down the energy gradient from NADH to O_2 .

What is the energy of activation of a chemical reaction, whose rate constant doubles, when the temperature is raised from 17^@C to 27^@C . Given: R = 8.314 Jk^(-1)mol^(-1) .

An air capacitor of capacity 50 mu F is charged to a potential of 200 V. The area of each plate is 20 cm^2 and the distance of separation between the plates is 0.1 mm, find the energy per unit volume of the electric field between the plates of the capacitor .

The reaction F_2(g) + 2ClO_2(g) is first order in each of the reactants. The rate of the reaction in each of the reactants. The rate of the reaction is 4.88xx10^(-4) M//s when [F_2] = 0.015M and [ClO_2] = 0.025 M . Calculate the rate constant of the reaction.

The correct increasing order of bond dissociation energy for N_2, O_2, F_2 and Cl_2 is

Complete the paragraph. square is the measure of energy trasfer when a forece (F) moves and object through a square (d). So when square is done, energy has been transferred from one enrgy store to another, and so: energy transferred= square done. Energy transferred and work done are both meassured in square (J).

A particle is executing SHM with amplitude A. At displacement x=(-A/4) , force acting on the particle is F, potential energy of the particle is U, velocity of particle is v and kinetic energy is K. Assuming potential energyh to be zero at mean position. At displacement x=A/2

A force F = (2 + x) acts on a particle in x-direction, where F is in newton and x is in metre. Find the work done by this force during a displacement from x = 1m to x = 2m

The figure shows the elliptical orbit of a planet about the sun S. An ellipse is the curve obtained when a cone is cut by an inclined plane. It has two focal points. The sum of the distances to the two focal points from every point on the curve is constant. F_1 " and " F_2 are the two focal points of the ellipse . The shaded area CF_1D is twice the shaded area AF_1B. t_1 is the time taken by the planet to move from C to D and t_2 is the time to move from A to B Which laws do we understand from the above diagram and description?

The rate constant of a first order reaction at 25^@C is 0.24 s^(-1) . If the energy of activation of the reaction is 88 kJ mol^(-1) , at what temperature would this reaction have rate constant of 4 xx 10^(-2) s^(-1) ?
