Identify the TRUE statement(s). Select all that apply. T(°C) P<sub>H?O</sub> (mmHg) 20 17.5 22 19.8 24 22.4 Check all that apply. Forgetting to correct the total pressure for P<sub>H?O</sub> pressure would lead to a higher calculated R value than the true value. P<sub>H?O</sub> increases with T; therefore neglecting to subtract P<sub>H?O</sub> from P<sub>T</sub> would cause greater error in a calculated R value at higher T. P<sub>H?O</sub> decreases with increasing T; therefore neglecting to subtract P<sub>H?O</sub> from the total pressure would cause smaller error in a calculated R value at higher T. Forgetting to correct the total pressure for P<sub>H?O</sub> would lead to a lower calculated R value than the true value. Do you know the answer? I know It Think so Unsure No Idea
