To determine the gas constant R, two students A and B perform an experiment based on the ideal gas equation given as P v = RT. Both use the same gaseous sample having v = 16.6 m3/mol and reported the approximate value of R as 8.3 J/(K∆mol) using the minimisation of sum squared error. The data collected by both the students are reported below. Choose the correct option: [4] P(T)(P a) 137 139 142 142 141 T(K) 274 276 278 280 282 Table 1: Data collected by student A. P(T)(P a) 137 141 142 148 145 T(K) 276 280 284 288 290 Table 2: Data collected by student B. |
