Answer:
the rate of change of = 10.0 M/s
the rate of change of = 20.0 M/s
Explanation:
Given that = 20.0 M/s
The equation for the reaction can be written as:
The rate of change of can be calculated as:
∴ the rate of change of = 10.0 M/s
The rate of change of can be calculated as:
∴ the rate of change of = 20.0 M/s

Answer:
50%
Explanation:
% yields =(experimental yields / theoretical yields ) x100%
= 122.1÷ 245.6 ) x100% = 50%
