Welcome to your Rate of Reaction Name Email Match them to their impact on reactants increase temperature catalyst increase concentration increase in surface area more reactants are exposed become more crowded they move faster create alternative pathway Match them to their impact on reactants decrease in concentration decrease in temperature small surface area Increase in pressure less crowded less particles are exposed more crowded less kinetic energy Arrange the method in order on how to measure rate of reaction of a gas Step 3 Step 6 Step 4 Step 2 Step 1 Step 5 Every 10 seconds, record the volume of gas produced Add 0.4 g of calcium carbonate to the flask. Immediately connect the gas syringe and start a stop clock Using a measuring cylinder, add 50 cm3 of dilute hydrochloric acid to a conical flask When the reaction is complete, clean the apparatus as directed by a teacher. Repeat steps 1 to 5 with different concentrations of hydrochloric acid Support a gas syringe with a stand, boss and clamp Arrange the method in order on how to measure rate of reaction by colour change Step 6 Step 3 Step 5 Step 4 Step 2 Step 1 Look down through the reaction mixture. When the cross can no longer be seen, record the time on the stop clock. Place the conical flask on a piece of paper with a black cross drawn on it. Using a different measuring cylinder, add 10 cm3 of dilute hydrochloric acid to the conical flask. Immediately swirl the flask to mix its contents, and start a stop clock. Repeat steps 1 to 5 with different starting temperatures of sodium thiosulfate solution. Measure and record the temperature of the reaction mixture, and clean the apparatus as directed by a teacher. Using a measuring cylinder, add 50 cm3 of dilute sodium thiosulfate solution to a conical flask. 1 out of 4 Time's upYou cannot switch tabs while taking this quiz!You are not allowed to switch tabs violation has been recorded.you cannot minimize full screen mode!You are not allowed to minimize full screen while taking this quiz, violation has been recorded.Access denied!
