The lizard in the photograph is not simply enjoying the sunshine or working on its tan. The heat from the sun’s rays is critical to the lizard’s survival. A warm lizard can move faster than a cold one because the chemical reactions that allow its muscles to move occur more rapidly at higher temperatures. A cold lizard is a slower lizard and an easier meal for predators. CHEMICAL KINETICS DEPENDENCE OF TEMPERATURE ON THE RATE OF A REACTION  CONCENTRATION AND RATE aA +bB cC+dD  EXPERIMENT TEMPERATURE TIME HIGH TEMPERATURE LOW TEMPERATURE  VIDEO EXOTHERMIC REACTIONS ENDOTHERMIC REACTIONS  2NO+O2 2NO2 FAST 2CO+O2 2CO2 SLOW Every 10 degree rise in temperature rate is doubled  When cooking food, temperature plays a crucial role in determining how quickly it cooks. Higher temperatures lead to faster cooking Higher temperatures accelerate the rate of oxidation of iron, resulting in the formation of rust. In various industries, such as pharmaceuticals, petrochemicals, and food production, temperature control is essential to ensure consistent product quality, increase reaction efficiency, and maintain safety. Graph of lnk vs 1/T EFFECT OF CATALYST ON RATE OF REACTION  RECAPTULATION Homework page 116-Q No's 4.7,4.8,4.9 page 120-Q No. 30
