"R_1 = 0.00543 \\\\\n\nT_1 = 40 + 273 = 313 \\;K \\\\\n\nT_2 = 80 +273 = 353 \\;K \\\\\n\n\\frac{R_2}{R_1} = Q_{10}^{ \\frac{T_2-T_1}{10}}"

For most biological systems Q10 is from 2 to 3.

Suppose "Q_{10} = 2"

"\\frac{R_2}{0.00543} = 2^{ \\frac{353-313}{10}}\\\\\n\n\\frac{R_2}{0.00543} = 2^{ 4} \\\\\n\n\\frac{R_2}{0.00543} = 16 \\\\\n\nR_2 = 0.00543 \\times 16 = 0.0869"

Answer: D. 0.0869 M/s
