3. 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)(Pa) 137 139 142 142 141 T (K) 274 276 278 280 282
Table 1: Data collected by student A. P(T)(Pa) 137 141 142 148 145
T (K) 276 280 284 288 290 Table 2: Data collected by student B.

Answer:
B has a better fit than A, hence correct
Step-by-step explanation:
A has a better fit than BB. The R2 of A is 0.643 and R2 of B is 0.837.
B has fit better fit than A. The R2 of A is 0.643 and R2 of B is 0.837 since R2 of A is less than R2 of B
B has a better fit than A, hence correct
since R2 do not match they do not have the same fit, hence incorrect
SSE of A is 6.7, not 14. hence it's also false.
SSE of A is 6.7, not 11.4 hence it's also false.
SSE of A and B are not 14 it's also false.
