3. Select the correct statement from the following choices that best explain the result recorded in the table as shown in question 1. O A The ratio of the effusion rate of hydrogen gas to that of methane gas is 3.20 B The molar mass obtained from experiment is lower than that of the actual molar mass of the gas A C. The molar mass obtained is different from the actual motar mass of Gas A due to the presence of impurities O D. The impurities presence might have the molar mass that is smaller than Gas A 4. What difference would you expect on the time of effusion and molar mass of gas Aif the experiment wvere carried out using the same apparatus at a higher temperature. A. At a higher temperature, gas molecules move inore rapidiy and effusion time would therefore longer B. At high temperature, the molar mass of gas A obtaned would be lower CAt high temperature, the ratio of effusion rate of hydrogen to gas A would be higher 0 At higher temperature, there is no change on the effusion rate of hydrogen gas to that of gas A
