Question

8.For a first order reaction (A) 4 points -products the concentration of A changes from 0.1M to 0.025 M in 4Ominutes. The rate of reaction when the concentration of A is 0.01 M is


​

Answer 1

Answer:

you increase the concentration of a reactant, there will be more of the chemical present. More reactant particles moving together allow more collisions to happen and so the reaction rate is increased. The higher the concentration of reactants, the faster the rate of a reaction will be. Hope you got your answer!

Answer 2

Answer:

All Excel formulas begin with an equal sign (=).

After the equal symbol, you enter either a calculation or function. For example, to add up values in cells B1 through B5, you can either.

Your 2 marks would be deducted if you you don't write (=) sign in formula because it's mandatory.
