Concept explainers
(a)
Interpretation:
The given calculation has to be performed and the answer has to be reported in proper number of significant figures.
Concept Introduction:
Significant digits:
In a number, the digits which contribute to the precision of the number are said to be significant digits.
Rules for determination of significant digits in a number:
- All non-zero digits are significant.
- The zeroes appearing between two non-zero digits are significant.
- The zeroes before the non-zero numbers are not significant.
- Zeroes after non-zero number without decimal are non-significant.
- Zeroes after non-zero number with decimal are significant.
- Zeroes after the decimal point are significant.
- Any numbers with scientific notation are significant.
The sum of the significant digits has to be given in the lowest decimal present in the values.
The significant digit in multiplication and division has to be given as the quantity with the fewest significant figures.

List the steps involved.arrow_forwardInstructions: Complete the questions in the space provided. Show all your work 1. You are trying to determine the rate law expression for a reaction that you are completing at 25°C. You measure the initial reaction rate and the starting concentrations of the reactions for 4 trials. BrO³¯ (aq) + 5Br¯ (aq) + 6H* (aq) → 3Br₂ (l) + 3H2O (l) Initial rate Trial [BrO3] [H*] [Br] (mol/L) (mol/L) | (mol/L) (mol/L.s) 1 0.10 0.10 0.10 8.0 2 0.20 0.10 0.10 16 3 0.10 0.20 0.10 16 4 0.10 0.10 0.20 32 a. Based on the above data what is the rate law expression? b. Solve for the value of k (make sure to include proper units) 2. The proposed reaction mechanism is as follows: i. ii. BrО¸¯ (aq) + H+ (aq) → HBrO3 (aq) HBrO³ (aq) + H* (aq) → H₂BrO3* (aq) iii. H₂BrO³* (aq) + Br¯ (aq) → Br₂O₂ (aq) + H2O (l) [Fast] [Medium] [Slow] iv. Br₂O₂ (aq) + 4H*(aq) + 4Br(aq) → 3Br₂ (l) + H2O (l) [Fast] Evaluate the validity of this proposed reaction. Justify your answer.arrow_forward
