"The rate constant for the reaction shown below is 1.64 *10-6/M·s.
NO2(g) + CO(g) NO(g) + CO2(g)
What is incomplete about this statement?
The rate constants of some reactions double with every 10 degree rise in temperature. Assume that a reaction takes place at 341 K and 351 K. What must the activation energy be for the rate constant to double as described?

What is incomplete about this statement?The incompleteness is missing the stated temperature. The rate constant depends on temperature.
What must the activation energy be for the rate constant to double as described?
ln (k1/k2) = -Ea/R (1/T1 - 1/T2)
ln 2 = - Ea/ 8.314 (1/ 351- 1/341)
Hence, the result follows.
