Created with Fabric.js 1.4.5 EXAMPLES A catalyst is a substance which changes the rate of reaction but is unchanged at the end of the reaction Loss of territories - productive land,industries and raw resources 3. 2. The Deutsche Mark lost 75% of it's value during WW1. It was after the war,however, when hyperinflationbegan Meat consumption dropped88% from pre-war levels = 50,000 deaths to starvation or hypothermia 1918 post pre Agricultural production dropped 16% Manganese dioxide, used to decompose Hydrogen Peroxide to Oxygen and Water. War Guilt RACHAEL HOUGHTON 1. Military restrictions Germany lost 13% of its land in the treaty,including 12% ofits population ADVANTAGES NOVEMBERCRIMINALS right wing (USPD) some supportedthe left wing Catalysts lower the activation energy required for a reaction to occur. This will mean that more molecules will have the energy to react. Both attempted revolutions: Atoms permenantly bonded to the surface men Sulfuric Acid is used to dehydrateEthanol to Ethylene with other restrictionsalso taking effect: The newly formed socialistgovernment was blamed- and branded the Sparticist Uprising Jan 1919 Kapp Putch Mar 1920 (Fatherland Party) Some supported the 1916 Cost of a loaf of bread: Nov 1923 - 200,000,000,000 D Marks Sept 1922 - 163 D Marks Catalysts in action 68% of zinc ore possessed 48% of ironore lost 26% of coalresources lost Catalysts in general lower reaction temperatures leading to lower production costs DISADVANTAGES Catalysts can be poisoned by waste products eg. sulphur in petrol and oil can reduce the properties of catalytic converters The reaction may be happening so fast, that errors may be made 2 H2O2(aq) O2(g) + 2 H2O(l)
