Answer:
Given space reaction space is comma straight A space rightwards arrow space straight B straight k space equals space 4.5 space cross times space 10 to the power of negative 3 end exponent space min to the power of negative 1 end exponent left square bracket straight A right square bracket subscript straight omicron space equals space 1 space straight M For space 1 st space order space reaction comma straight k space equals space fraction numerator 2.303 over denominator straight t end fraction space log space fraction numerator 1 over denominator left parenthesis straight a space minus space straight x right parenthesis end fraction At comma space straight t space equals space 60 4.5 space cross times space 10 to the power of negative 3 end exponent space equals space fraction numerator 2.303 over denominator 60 end fraction space log space fraction numerator 1 over denominator left parenthesis straight a space minus space straight x right parenthesis end fraction So comma space left parenthesis straight a space minus space straight x right parenthesis space equals space 0.7634 Rate space after space 60 min space equals space straight k space left parenthesis straight a space minus space straight x right parenthesis space equals space 4.5 space cross times space 10 to the power of negative 3 end exponent space cross times space 0.7634 space equals space 3.4354 space cross times space 10 to the power of negative 3 end exponent
