<h3><u>Answer and explanation;</u></h3>
-Rate of reaction is the speed at which the reactants are converted to products.
-Rate of reactions depends on a number of factors which includes<u>;</u>
- <em><u>Concentration of reactants</u></em>;<u><em> increasing the concentration of reactants</em></u> increases the rate of reaction.
- <u><em>Temperature;</em></u><u><em> </em></u>An <u><em>increase in temperature results to an increased rate of reaction.</em></u> Increase in temperature increases the kinetic energy of molecules thus the collision per unit time also increases and hence the rate of reaction increases.
- <u><em>Decreasing the size of particles of solid reactants</em></u> also increases the rate of reaction. This is because smaller particles increases the surface area on which more collisions can occur thus a faster rate of reaction.
- <em>Adding a catalyst also increases the rate of reaction.</em> This is because catalysts lower the activation energy of reactants, minimum energy require by reactants for the reaction to take place. This thus increases the rate of reaction.
The direction of the magnetic field at point Z ; INTO THE SCREEN
Answer:
is there any choice? in this question?
Answer:
force on electron will be equal to 
Explanation:
We have given magnitude of electric field E = 600 N/C
Charge on electron 
We have to find the electric force on the electron
Force in electric field is equal to 
, here q is charge and E is electric field
So force will be equal to 
So force on electron will be equal to
The applicable answer/s are
- Electroscopes can measure the amount and type of charge, not to explicit to only one but both. and it is not made of of insulating materials instead it is made up of conductive materias.
