Famine is a more complex problem than a shortage of things to eat; it is a challenge of market and distribution, the result of a long, slow decline in access to food. That decline may occur for any number of reasons, including natural disasters, politics, repressive governments, and poor management of resources. The famine cycle may be triggered by a natural disaster, but is often exacerbated by man-made issues, such as reduced wages and/or rising food prices.
Temperature. Usually, an increase in temperature is accompanied by an increase in the reaction rate. Temperature is a measure of the kinetic energy of a system, so higher temperature implies higher average kinetic energy of molecules and more collisions per unit time.here are several factors that can influence chemical reaction rate. In general, a factor that increases the number of collisions between particles will increase the reaction rate and a factor that decreases the number of collisions between particles will decrease the chemical reaction rate.
If you increase the temperature from 293 K to 303 K (20Â°C to 30Â°C), you will increase the collision frequency by a factor of: That's an increase of 1.7% for a 10&deg rise. The rate of reaction will probably have doubled for that increase in temperature-in other words, an increase of about 100%.The effect of increasing collision frequency on the rate of the reaction is very minor.The important effect is quite different. . .HE EFFECT OF TEMPERATURE ON REACTION RATES This page describes and explains the way that changing the temperature affects the rate of a reaction. It assumes that you are already familiar with basic ideas about the collision theory, and with the Maxwell-Boltzmann distribution of molecular energies in a gas.
