For a certain equilibrium reaction, the equilibrium constant remains constant at every given temperature. Changes in temperature, pressure, or reactant/product concentrations can disrupt the equilibrium, causing movements in the equilibrium position to re-establis...
Does a proportional relationship have a constant rate of change? Is the relationship between the magnetic force and current linear? Is tension force perpendicular? A wave along a string has the following equation, where x is in metres and t is in seconds: y = 0.04 \sin(...
On a calibration curve for Abs vs Concentration, explain how to determine the sensitivity or how to calculate it. What is the advantage of reading the absorbance rather than the percent transmittance on a spectrophotometer? Explain how measuring absorbance allows us to meas...
In the end, the effect of temperature on reaction rate is determined through its effect on the rate constant k, which in turn depends on the **activation energy Ea**of the reaction in question. Higher temperatures will see a higher fraction of molecules attain this minimum kinetic energy need...
Guests can use star ratings to rate the features of their stay with respect to cleanliness, location, and convenience of the property. Airbnb has experienced very rapid growth. In April 2018, more than two hundred million guests across the world had used Airbnb, with four million nights of ...
The regional-level variables include economic development level, demographic structure and market concentration. To be specific, economic development level is represented by the logarithm of per capita GDP; demographic structure means the rate of agricultural population in total population; market ...

How does concentration affect the rate of reaction? Consider the reaction: N_2(g) + 3H_2(g) rightarrow 2NH3(g) If the rate of the loss of hydrogen gas is 0.03 mol/L-s, what is the rate of production of ammonia? How does pressure affect equilibrium constant?
Why does temperature stay constant during a phase change? Why does the temperature remain constant for boiling water? Why is the dry adiabatic lapse rate constant? Why does evaporation lower the temperature of a liquid? Why can't cold-blooded animals produce heat?
