Math Help - Rate of reaction question involving an oven

"When the gas to a stove is turned on, the gas does not burn unless lit by a flame. once lit, however, the gas burns until turned off. Explain these observations in terms of the effect of temperature on reaction rate."

Can someone answer this question for me please?

Temperature speeds up reaction rate. Until you had the high temperature (flame) the reaction (gas burning) couldn't happen. The temperature is then more or less constant unti the gas runs out, and then the reaction stops but not due to temperature, just due to lack of reactant....
