Answer #1

Volume of reactants should be kept constant to do a fair test and comparison of results.eg. If you are testing for the effect of increasing surface area, the volume of reactants should be kept constant.

Other reason is because reactions can be concentration dependent. Side reactions producing by-products can be favored if a reaction is performed either more dilute or more concentrated than optimal. Yes, reaction volume does relate to concentration since concentration is in g/mL.

When attempting to determine the coefficient of kinetic friction, why is it necessary to move the block with constant velocity? When attempting to determine the coefficient of static friction, why is it necessary to measure the applied force just before the block moves? Are these two scenarios (constant velocity and almost in motion) the only scenarios when friction is present? Explain your answer.
