What is the general equation for mean rate of reaction?
Mean rate = quantity of reactant used up or product formed ÷ time taken.
What is the equation for mean rate using mass?
Mean rate = mass of reactant used or product formed ÷ time taken.
What is the equation for mean rate using gas volume?
Mean rate = volume of gas produced ÷ time taken.
What is the equation for mean rate using moles?
Mean rate = amount of reactant used or product formed (mol) ÷ time taken.
What is the equation for calculating the gradient of a graph?
Gradient = change in y ÷ change in x.
What is the equation for calculating instantaneous reaction rate from a graph?
Instantaneous rate = gradient of the tangent at that point.
What are the units of rate when mass is measured in grams and time in seconds?
g
What are the units of rate when volume is measured in cm³ and time in seconds?
cm³
What are the units of rate when amount is measured in moles and time in seconds?
mol
