The product of pressure and volume has the same si base units as?
Energy
Why does constant Kc in chemical equilibrium has no units?
Kc is the equilibrium constant and is the ratio of the activity of the reactants (numerator) to the activity of the product (denominator). The activity of each component is raised to the power of its corresponding chemical stoichiometric coefficient. Since the activity of each chemical is unitless, the equilibrium constant will also have no units. Example: For equilibrium of chemicals in the gas phase, each activity will be measured by its partial pressure (units of pressure) multiplied by its fugacity (units of 1/pressure), so the activity of each gas participating in the equilibrium will be unitless, and the corresponding ratio (Kc) will be unitless.
What is true if a liquid and gas are equilibrium?
The rate of evaporation is the same as the rate of condensation.
As partial pressure increases what happens to the rate of diffusion?
Rate of diffusion will increase.
How does increasing pressure affect the reaction rate?
The concentration of reactants is changed.
Calculation of rate-pressure product?
Rate-pressure product = Heart rate * Systolic pressure
What does rate pressure product indicate physiologically?
Rate pressure product indicates the amount of stress being placed on the heart muscle. The measure is taken by multiplying the heart rate with the systolic blood pressure.
The product of pressure and volume has the same si base units as?
Energy
Injection speed?
Resin pressure Resin pressure has a great influence on the shrinkage rate. If the resin pressure is large, the shrinkage rate becomes smaller and the size of the product is larger.Even in the same mold cavity, the resin pressure varies depending on the shape of the product, so the shrinkage rate varies.
Another name for rate-pressure product?
Myocardial Oxygen demand
Why does an exercise physiologist calculate pressure rate product?
Rate-pressure product is a good estimate of myocardial oxygen demand. RPP = Heart Rate X Systolic Blood Pressure. When using the RPP with patients with Coronary Artery Disease and with angina symptoms, it can indicate the oxygen demand at which Angina initially occurs (angina threshold).
Why is pressure a derived quantity?
In the SI system, because that's the way it is defined. Pressure is defined as force divided by area. SI units are newton / square meter, this derived unit is called the pascal. This is the way it is defined in the SI, and in some other systems of units. You could just as well create a system of units in which pressure is a base unit, and force is derived (as the product of pressure x area). The decision, which units are base units and which units are derived, is more or less arbitrary.
How many units are in a rate?

How do you fnd a unit rate?
By dividing something. What you divide will depend on what unit rate you want to find. As an example, let's assume that a dozen (12 units) of a certain product cost $48. If you divide $48 by 12 units, you have a unit rate of 4 dollars/unit. (In principle, you can also divide the other way round; in that case you have 1/4 units/dollar.)
What is single absorption rate in cost accounting?
Single absorption rate is overall rate to allocate overheads to units of product based on some other base like machine hours or direct labor hours etc.
How do you get a rate as a fraction?
Simplify the fraction to its simplest form.If this is 1/y then the unit rate is "1 unit per y units".If it is x/1 then the unit rate is "x units per unit".If it is x/y then the units rate is "(x/y) units per unit".
Why overhead absorption rate is important?
In absorption costing, overhead absorption rate or blanket rate is key to spread all overheads on production of volume of product, because if we don't have the overhead absorption rate manufacturing overhead cannot be spread or there is no basis for allocation of overheads on manufactured units.
