equation
Expression has no answer. a equation has an answer
If there is no = sign it is an expression but if there is an = sign it is an equation
An equation is a ploblem with no answer and an expression is a problem with an answer so you'll get different answers with an equation and an expression.
equation is an expression equated to a value..what you have written is an expression. when equated to a value or any other expression makes it an equation.
Rate = k[A]m[B]n
equation
The question contains an expression, not an equation. An expression cannot have a unit rate.
Equation
formula
The chemical equation is the word expression of a chemical reaction.The rate of reaction give information about the speed of this reaction.
They are experimentally determined exponents.

y - 7x is not an equation, it is an expression. An expression cannot have a slope.y - 7x is not an equation, it is an expression. An expression cannot have a slope.y - 7x is not an equation, it is an expression. An expression cannot have a slope.y - 7x is not an equation, it is an expression. An expression cannot have a slope.
An equation that relates the reaction to the concentrations of the reactants
You need to know the rate of the reaction, as well as the concentrations of all reactants. Then you plug those values into the equation of rate = k[A][B] or whatever the rate equation happens to be.
The equation is:PV = k, where:P - pressureV- volumek - constantThis law is valid at constant temperature.
