Answer:
C. Gamma > beta > alpha
Explanation:
<u>Alpha rays</u> : These are positively charged and have mass 4u. These contain high energy Helium nucleus with 2 proton and 2 neutron.
These are heavier and maximum charged than beta and gamma particles.They have low velocity,least penetration power (can't travel more than 10-18 cm).
<u>Beta rays</u> : They are negatively charged and have negligible mass.
On emmission of beta particle, neutron is divided into proton and electron. They have less mass and very high velocity, so their penetrating power is more than alpha particles.
<u>Gamma rays</u>: These are parts of electromagnetic spectrum and travel with the speed of light (maximum velocity).Gamma rays do not have mass have maximum penetrating power.

Explanation:
Hello!
In this case, for the reaction:
In such a way, via the rate proportions, that is written considering the stoichiometric coefficients, we obtain:
Whereas the reactants, CO and H2 have negative stoichiometric coefficients; therefore the rate of disappearance of hydrogen gas is related to the rate of appearance of methanol as shown below:
Which means that the rate of disappearance of hydrogen gas is negative and the rate of appearance of methanol is positive.
