Question

I did an experiment and these are the results of the pH for these temperatures. I used 2mL of 1.0 M NaOH and 15mL of acetic acid (5% Distilled White Vinegar). Could you please explain and show me how to do the calculations for the rest of the table? Thank you!

pH T (°C) T(K) In(K,) 1/T (K1) 4.14 4.24 4.33 4.47 4.62 303 298 293 288 283 30 20 3 10
