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.
There 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.here are several factors that can influence chemical reaction rate.

Each chemical reaction, under specific reaction. conditions, proceeds at a characteristic speed called the rate. Reaction rate is defined as. the increase in molar concentration of a reaction product per unit time or as a decrease in. the molar concentration of a reactant per unit time (see Equation 2). The rates of chemical. reactions vary considerably depending on the reaction conditions and on the nature of the.
